Men's orgasms, on the other hand, are generally seen as unproblematic unless they occur too soon during coitus coitus /co·i·tus/ (ko´it-us) sexual connection per vaginam between male and´ital

However, there has been little research at a population level that examines predictors of or factors associated with orgasm on any one occasion. Indeed, much of the research on female difficulties with orgasm or with heterosexual sex in general has focused more on indirect causes, such as upbringing up·bring·ing

The British National Survey of Sexual Attitudes and Lifestyles The National Survey of Sexual Attitudes and Lifestyles (NATSAL) is the name given to two face-to-face interviews of people in the United Kingdom regarding their sexual behaviour and patterns. The two rounds of interviews are NATSAL I (1990-91) and NATSAL II (2000-01).  (Johnson, Wadsworth, Wellings, Field, & Bradshaw, 1994) focused largely on data required for the epidemiological epidemiological

The American study of the social organization of sexuality (Laumann, Gagnon, Michael, & Michaels, 1994), which took a broader, more sociological look at sexual conduct, asked about frequency of orgasm in the past 12 months. Among women (but not men), reporting orgasm rarely or never was associated with being unhappy (p. 358).

 diversity was found to be age-dependent, with younger respondents engaging in a higher number of practices. Despite the large number of possible combinations of these practices (even if the number is reduced by counting manual stimulation of either partner as one practice, and cunnilingus and fellatio as oral sex), patterns of practice were not diverse. Three repertoires or combinations of practices accounted for three fourths of all encounters: caresses and vaginal intercourse; caresses, partner masturbation, and intercourse; and the previous three plus oral sex.

The Finnish national survey carried out in 1991 was able to compare its results with a similar survey done in 1972 and found an increase in sexual satisfaction (Haavio-Mannila & Kontula, 1997). The evaluation of the most recent intercourse as pleasurable increased among women, reducing the gender gap, but men still enjoyed intercourse in general more than women. At most recent intercourse, 92% of men and 56% of women in the later survey achieved orgasm. The authors constructed a model to find factors related to physical sexual satisfaction and found that women's sexual satisfaction was better predicted by factors in the model: the path models explained only 21% of men's but 46% of women's satisfaction with sex.

Data have already been published from the Australian Study of Health and Relationships on the frequency of sexual activities The frequency of sexual activity of humans is determined by several parameters, and varies greatly from person to person, and within a person's lifetime.

The frequency of sexual intercourse might range from zero (sexual abstinence) for some to 15 or 20 times a week.

However, that analysis was simply descriptive and made no attempt to examine the relationship between sexual repertoire and orgasm. This article explores that relationship.

We stress, however, that the data collected in this study on sexual practice at last encounter were selective, with the choice of questions driven largely by relevance to health concerns about penetrative sex and condom 1. condom - The protective plastic bag that accompanies 3.5-inch microfloppy diskettes.

The methods used in the Australian Study of Health and Relationships are described in detail elsewhere (Smith, Rissel, Richters, Grulich, & de Visser, 2003). Briefly, between May 2001 and June 2002, computer-assisted telephone interviews were completed by a representative sample of 10,173 men and 9,134 women aged 16-59 years from households in all states and territories of Australia The states and territories of Australia make up the Commonwealth of Australia under a federal system of government.

Factors Possibly Associated with Orgasm

Demographic factors used were age (recoded into 16-19, 20-29, 30-39, 40-49, 50-59); language spoken at home (English, other); education (less than secondary, secondary, post-secondary); household income (low < $20,000 per year, moderate $20,000-$52,000 per year, high > $52,000 per year); occupational classification (blue-collar, white-collar, manager/professional); religion or faith (yes, no).

Measures of lifetime sexual experience included age at first vaginal intercourse or oral sex (recoded as < 16 years or [greater than or equal to] 16 years); number of years sexually active (recoded as 0-2 years; 3-10 years; 11-20 years; 21 + years); total number of sexual partners over the lifetime (recoded as 0-2; 3-10; 11-20; 21+).

Sexual permissiveness was measured by six items that formed a scale with good internal consistency In statistics and research, internal consistency is a measure based on the correlations between different items on the same test (or the same subscale on a larger test). It measures whether several items that propose to measure the same general construct produce similar scores.  (Cronbach's [alpha] = 0.74; Rissel, Richters, Grulich, de Visser, & Smith, 2003). Scores ranged from 1 to 5, with higher scores indicating more permissive permissive adj. 1) referring to any act which is allowed by court order, legal procedure, or agreement. 2) tolerant or allowing of others' behavior, suggesting contrary to others' standards.

 attitudes. These raw scores were recoded into low (> 1 SD below the sample mean), moderate, and high (> 1 SD above the sample mean).

Measures of recent sexual activity included: masturbated in the last month (yes, no); deliberately visited internet sex site in the last year (yes, no); watched X-rated film in the last year (yes, no); used sex toys sex toy Sexology Any device used during sexual activity to enhance pleasure Examples Chains, dildos, special condoms, edible undergarments, whip Per Cicero O tempora! O mores!  in the last year (yes, no); frequency of sex in the last four weeks (no sex, up to twice a week, more than twice a week).

Respondents indicated their relationship to their most recent sexual partner (regular, other). Those who had sex with a regular partner indicated the length of their relationship with this partner (less than 1 year, 1-2 years, 2-5 years, 5-10 years, 10-20 years, 21+ years).


Data were weighted to adjust for the probability of household selection (households with more phone lines were more likely to be contacted) and to adjust for the probability of selection within a household (individuals living in households with more eligible people were less likely to be selected). Further weighting on the basis of age, gender, and area of residence ensured that both the full sample and the subsample matched the Australian population as reported in the 2001 Census (Smith et al., 2003). Weighted data were analyzed using the survey estimation estimation

Practices at Last Sexual Encounter

As reported by de Visser et al. (2003), vaginal intercourse was the most common practice, engaged in by 95% of respondents. For the convenience of readers, these findings are repeated in Table 1, together with the odds ratio for the difference between men's and women's responses. It was more common for men to report manual stimulation of their female partner and cunnilingus than for women to report receiving such stimulation, but the differences were not huge and the picture was roughly consistent: in about three fourths of encounters, the respondent In Equity practice, the party who answers a bill or other proceeding in equity. The party against whom an appeal or motion, an application for a court order, is instituted and who is required to answer in order to protect his or her interests.  received manual sex, and in about a one fourth, the respondent received oral sex. Anal intercourse occurred in less than 1% of encounters.

Combinations of Sexual Practices

Table 2 displays the combinations of sexual practices engaged in during respondents' most recent heterosexual encounters. Of the 64 possible combinations of these six practices, men engaged in 40 and women engaged in 35.

The behavior of half of the men (49.9%) was captured by two combinations: vaginal intercourse plus mutual manual stimulation (35.3%) and the same combination with mutual oral sex as well (14.6%). The next most common combinations were vaginal intercourse with manual stimulation of the woman (10.8%) and vaginal intercourse alone (9.6%).

The behavior of nearly half (48.2%) of the women was similarly captured by two combinations: vaginal intercourse plus mutual manual stimulation, and vaginal intercourse alone. The next most common combinations were vaginal intercourse plus mutual manual and oral sex (11.4%), and vaginal intercourse plus manual stimulation of the woman (9.8%).

Prevalence of Orgasm During Most Recent Sexual Encounter

At their last sexual encounter, 94.8% of men and 68.9% of women had an orgasm. Table 3 displays associations between orgasm during the most recent heterosexual encounter and demographic variables. A man was significantly less likely to have had an orgasm during his most recent sexual encounter if he was aged 16-19 (p = .004). There was no significant association between whether men reached orgasm during their most recent sexual encounters and language spoken at home (p = .134); education (p = .093); household income (p = .273); occupational classification (p = .474); or religious belief (p = .308).

A woman was significantly less likely to have had an orgasm during her most recent sexual encounter if she was aged 16-19 or 50-59 (p = .010). She was significantly more likely to have had an orgasm during her most recent sexual encounter if she spoke English at home (p = .008); had completed post-secondary education (p = .022); had a higher household income (p = .002); and had a managerial/professional occupation (p = .017). The likelihood of orgasm was not related to having a religion or faith (p = .378).

Table 4 displays associations between orgasm during the most recent heterosexual encounter and sexual history variables. Men were significantly less likely to have had an orgasm during their most recent sexual encounter if they had been sexually active for two or fewer years (p = .010), had less permissive attitudes toward sex (p = .031), or if the encounter was with an occasional or casual partner rather than a regular one (p < .001). They were significantly less likely to have had an orgasm if they had been in the relationship with the regular sexual partner for less than one year or for between two and five years, but most likely to have had an orgasm with a regular partner of between one and two years' standing (p = .017). Whether men had an orgasm during the most recent sexual encounter was not significantly related to whether they became sexually active before age 16 (p = .976), the number of sexual partners they had had over the lifetime (p = .273), whether they had masturbated in the last month (p = .767), had deliberately visited an internet sex site in the last year (p = .671), watched an X-rated video or film in the last year (p = .419), or had used sex toys in the last year (p = .129).

Women were significantly less likely to have had an orgasm during their most recent sexual encounter if the encounter was with a non-regular sexual partner (p < .001). They were significantly more likely to have had an orgasm if they had used a sex toy in the last year (p = .044) or had sex more than twice a week in the four weeks before being interviewed (p = .003). Women in relationships of one to two years' standing were the most likely to have an orgasm (p = .024). Whether women had an orgasm during the most recent sexual encounter was not significantly related to whether they had become sexually active before age 16 (p = .651), the length of time they had been sexually active (p =. 144), the number of sexual partners over the lifetime (p = .455), whether they had masturbated in the last month (p = .671), had deliberately visited an internet sex site in the last year (p = .352), had watched an X-rated video or film in the last year (p = .511), or their attitudes toward sex (p = .424).

Orgasm and Sexual Practice

Table 5 shows the association between the likelihood of orgasm and the number of sexual practices engaged in during the most recent heterosexual encounter. Both men (p < .001) and women (p < .001) were more likely to have an orgasm if they engaged in a greater number of sexual practices, with orgasm most likely in encounters in which five practices were experienced. For both men and women, when the analyses were adjusted to account for the effect of factors identified as significantly associated with orgasm (see Tables 3 and 4), the patterns of results and the sizes of the odds ratios did not change. This suggests that the association between number of sexual practices and orgasm is independent of the influence of demographic factors and sexual history.

For men, the likelihood of orgasm was not strongly influenced by the number of sexual practices, probably because of the high proportion of men having orgasms from a single practice, usually vaginal intercourse. For women, the results were different and suggested that it is only when practices such as oral and manual stimulation are added to vaginal intercourse that women become more likely to have an orgasm.

In order to investigate this further, we looked at the likelihood of orgasm for the more common combinations of practices (Table 6). For simplicity, we excluded those practices where the respondent stimulated the partner (i.e. manual stimulation of the partner, cunnilingus for men, and fellatio for women). These practices may be arousing but are intuitively unlikely to lead directly to orgasm for the respondent.

Almost all men reached orgasm in encounters that included vaginal intercourse. Fewer men, but still over 80%, reached orgasm in encounters where they received oral and/or manual stimulation but did not have intercourse Verb 1. have intercourse - have sexual intercourse with; "This student sleeps with everyone in her dorm"; "Adam knew Eve"; "Were you ever intimate with this man?" . The picture for women was quite different: orgasm was least likely (50%) among the group whose only reported practice was vaginal intercourse. Rates were higher (around 70%) among those who had intercourse plus manual stimulation, or intercourse plus cunnilingus. But orgasm was more likely for those who had intercourse and also received both manual and oral stimulation; indeed, it appeared to be most frequent among the small number of women who received such stimulation but did not have intercourse, though numbers for some combinations were too small to permit significance testing.


This study was based on a large national representative sample with a high response rate (73.1%). Although prevalence estimates from such studies are likely to suffer some residual bias due to higher refusal rates among more embarrassed and less sexually active respondents--the "sex survey volunteer effect"--this is a minimal issue for this analysis based on the last sexual encounter in the previous year. People who had not had sex in the past year were not asked these questions.

More women (1.9%) than men (0.5%) reported sexual encounters including none of the six practices we asked about. This suggests that women may be more likely to count activities as sex when they do not include intercourse, though such a suggestion is not supported by other research. In the French national survey (Messiah et al., 1995), 99% of encounters reported by both men and women included intercourse, and in three studies of university students in different countries, men were more likely than women to count non-coital activities as "sex" (Pitts & Rahman, 2001; Richters & Song, 1999; Sanders San´ders

n. 1. An old name of sandalwood, now applied only to the red sandalwood. See under Sandalwood.
 & Reinisch, 1999).

Men were more likely to report all the practices asked about, particularly those that they did to their partner (manual stimulation of the vaginal area and cunnilingus) rather than those received from the partner (manual stimulation of the penis and fellatio). It may be that women regard some manual or oral stimulation received from their partners during foreplay as too perfunctory per·func·to·ry

 to report, or the men's responses may be subject to social desirability bias Social desirability bias is the inclination to present oneself in a manner that will be viewed favorably by others. Being by nature social creatures, people are generally inclined to seek some degree of social acceptance, and as with other psychological terms, "social desirability" . However, the data allow us to form a view of the most common sexual encounter between men and women in Australia. It consists of vaginal intercourse preceded, accompanied, or followed by the partners stimulating each other's genitals gen·i·tals
 by hand. At their most recent sexual encounter, about half the respondents had vaginal intercourse plus manual stimulation of either or both partners. About a third had vaginal plus manual plus oral sex (given and/or received), and 12% had only vaginal intercourse. Only around 7% had any other combination, including "none of the above" (i.e., they had sex but not any of the practices we asked about), oral or manual sex without vaginal intercourse, and any combinations including anal sex. Although the percentages are not directly comparable because we did not ask about "caresses," the finding of a lack of repertoire diversity is broadly similar to the French survey (Messiah et al., 1995). Despite the fact that a range of possible practices was not asked about, the heavy concentration on a few of the many possible combinations of the six practices we did ask about suggests that a fairly limited "script" for sex is well-established (Gagnon & Simon, 1974).

Other practices that people may have done at their last sexual encounter but which were not asked about include hugging and kissing, licking Licking, river, c.320 mi (515 km) long, rising in E Ky. and flowing NW to the Ohio River opposite Cincinnati; the North and South Forks are its chief tributaries.  or stroking non-genital areas of the body (including nipples or anus), "dry humping Humping could refer to:

Later in the questionnaire, respondents were asked about their experience of role-play or dressing up, use of sex toys, bondage and discipline, group sex, digital anal stimulation, rimming, and fisting in the past year. The most common of these were digital anal stimulation, reported by 17.3% of men and 14.3% of women, and use of a sex toy, reported by 11.8% of men and 14.1% of women. Each of the other practices was engaged in by less than 5% of respondents (Richters et al., 2003b). It is unlikely, therefore, that any of these practices form a large part of the regular sexual interactions between heterosexual couples. Hugging, kissing, and perhaps massage massage (məsäzh`), treatment of superficial parts of the body by systematic rubbing, stroking, kneading, or slapping. Massages can be administered manually or with mechanical devices. , stroking, or licking other parts of the body are more likely to form part of the standard heterosexual encounter.

Demographic and relationship characteristics were associated with orgasm, but the differences were not as dramatic as the associations with gender and with sexual practice. The exception is what appears to be a learning effect: men and women under 20 and men with less than three years' sexual experience were less likely to have an orgasm. (Less experienced women also appeared to have a lower likelihood of orgasm, but the difference did not reach statistical significance.) The nature of the relationship in which the sex occurred also had a strong effect: less than half of the women having sex with a casual or occasional partner reached orgasm.

The associations between orgasm and demographic characteristics suggest a social class effect, with better-educated, non-immigrant women more likely to have orgasms. The effect of sexual permissiveness was weak--indeed non-significant in women--though the association between use of sex toys and orgasm in women may indicate a link between orgasm and sexual interest or adventurousness Adventurousness

 component, but is probably compounded by an age-cohort-related cultural limitation of sexual practice.

It is unusual for a man not to have an orgasm when he has sex with a woman: only 5.2% of men did not reach orgasm at their last heterosexual encounter. It is much more common for women, 31.1% of whom did not reach orgasm. This difference is reflected in the survey's findings on sexual difficulties, which showed that women were much more likely than men to have trouble reaching orgasm (Richters et al., 2003c).

One reason for this may be the heavy concentration on vaginal intercourse as the central, almost compulsory sexual practice, which is more effective as a way for men to reach orgasm than for women. This conjecture CONJECTURE. Conjectures are ideas or notions founded on probabilities without any demonstration of their truth. Mascardus has defined conjecture: "rationable vestigium latentis veritatis, unde nascitur opinio sapientis;" or a slight degree of credence arising from evidence too weak or too  was confirmed when we examined the relationship between combinations of sexual practices and orgasm in Tables 5 and 6. In general, men were highly likely to have an orgasm in any encounter that included vaginal intercourse, but were somewhat less likely to do so if they only received oral and/or manual sex. Nonetheless, among men whose partners stimulated them manually or performed fellatio as well, more than 80% had an orgasm. In contrast, women who had vaginal intercourse but no oral or manual stimulation had only a 50% chance of reaching orgasm. Among those who had vaginal intercourse and whose male partners also stimulated them manually--the largest group--71% had an orgasm. Few people had anal intercourse, but it did not seem to make much difference in the likelihood of orgasm for men or women.

Although women were more likely to reach orgasm when the encounter included manual and oral sex, their orgasms did not necessarily occur during these practices. Some encounters may be based on the understanding of fairness or reciprocity reciprocity

The third orders are chiefly supplements of the friars—Franciscans (the most numerous), Dominicans, and Carmelites.  educated). One man summarized this script as "usually she will come first, I go down on her and then later I'll come inside her." It is also probable that some women are more likely to reach orgasm during intercourse if they have been highly aroused by other practices first. Braun et al. suggested that there were limits to the discourse of reciprocity: the man's orgasm tends to "signal an end to 'sex'" (p. 247); if the woman wants further stimulation after this, she needs to claim it explicitly.

We cannot assume, of course, that everyone having sex wants to reach orgasm on that occasion. Although there is evidence that women who have frequent orgasms are more likely to be satisfied with their sex lives (Haavio-Mannila & Kontula, 1997), it does not matter to everyone. Women who had sex more than twice a week in the past four weeks were more likely to have an orgasm at their last encounter, but the difference was not large.

One possible explanation for the discrepancy DISCREPANCY. A difference between one thing and another, between one writing and another; a variance. (q.v.)
     2. Discrepancies are material and immaterial.
 between male and female experience of orgasm in partnered encounters is that men want sex more often than women, with the result that in established couples, some of the sexual interactions are what women popularly call "mercy fucks" or "freebies." When asked how often they would ideally like to have sex, men's stated ideal frequency was somewhat higher than women's. The median response from men was four to six times a week, whereas the median response from women was in the "two or three times a week" category. Only 3.4% of men but 10.1% of women wanted sex less than once a week, and 24.3% of men but only 8.3% of women wanted sex daily (Richters et al., 2003a). This means that there are likely to be more relationships in which the man wants sex more often than the woman than vice versa VICE VERSA. On the contrary; on opposite sides. . (Note that this does not necessarily mean the woman wants less sex; she may desire longer or more elaborate sessions rather than daily "quickies.")

 the man, and some of the no-intercourse events consisting of manual and oral stimulation of the woman may be occasions on which the man, uninterested in reaching orgasm himself, is obliging the woman.

If we return to the sexual practice findings with this in mind, we see that nearly 12% of reported sexual encounters consisted of vaginal intercourse alone, with a high chance of orgasm for the man but a comparatively low chance for the woman. The putative Alleged; supposed; reputed.

 counterpart of this encounter for women is manual stimulation, or manual stimulation plus cunnilingus, reported by less than 0.3% of respondents. It is hard to escape the conclusion that when the man is keen to have sex but the woman is not, intercourse ensues and the man reaches orgasm, but when the woman is keen but the man is not, sex rarely happens.

Another possible explanation for the discrepancy between male and female experience of orgasm in partnered encounters is that women are intrinsically less keen on sex than men and/or less physiologically phys·i·o·log·i·cal   also phys·i·o·log·ic

 capable of reaching orgasm. There may be evolutionary reasons for this. Nonetheless, in cultures that support and encourage female sexual pleasure, women do often reach orgasm and appear to enjoy sex more and be happier if they do so. Our findings suggest that manual and oral sex provide the direct stimulation for many women that makes orgasm more likely, though still less likely than for men. Women having sex with women were more likely to reach orgasm at their last encounter (76%) than women with male partners (69%), though this is still a lower proportion experiencing orgasm than among men with male partners (89%; Grulich, de Visser, Smith, Rissel, & Richters, 2003).

All of these comparisons, however, make the naive assumption that orgasms are qualitatively all the same and can simply be counted, and that more is better. Sex therapist Bernard Apfelbaum (personal communication) has argued that we should not see men's greater number of orgasms as an unalloyed un·al·loyed

 women's sexual difficulties to create a market for a "pink Viagra" (Moynihan, 2003; Wyllie, 2005) and the arguments against this (Kaschak & Tiefer, 2001) have drawn attention to the issue.
