Q I HAVE been with my girlfriend for four months but we have never made love. She seems very embarrassed by her body and will not let me undress her, although she is very affectionate and wants us to stay together. Am I doing something wrong?

AFrom sex therapist Philip Hodson, author of How To Make Great Love To A Woman: Many women can be nervous about showing their body because they have low self-esteem or believe they are ugly. These beliefs can be due to misconceptions about their weight, or stem from a verbally abusive parent or past boyfriend, or sometimes can be linked to depression.

You should move with care and consideration, as there is clearly something wrong with her opinion of herself. Try soft, discreet lighting.

And try not to stare at her body too much - keep your eyes on her face so she doesn't feel you are scrutinising her nakedness.

QI HAVE acne and probably eat too much chocolate and too many chips. Could this affect my skin, and what can I do about it?

A From pharmacist Nick Mortimer, at Lloyds pharmacy: Extensive scientific studies have failed to find a link between diet and acne. Nonetheless, some people find certain foods affect their acne, so it's worth eating a healthy, balanced diet.

There are other things you can do to help. Firstly, wash your face twice daily and don't use perfumed products.

The new age of anti-acne treatments are more effective than ever and, providing you use an appropriate treatment for your skin type, you should see an improvement after a month. But speak to your pharmacist as not all may be suitable for your skin.

If the acne is more serious, you might need to see a skin specialist about possible medical or laser treatments.

Try not to pick or squeeze the spots, as this spreads and worsens the infection. Try to avoid having a fringe, as they can irritate the forehead.

Q I HAVE two young children and find it difficult to make sure they eat enough fruit and vegetables. They do drink fruit juices but I've read that this might damage their teeth. Is this right?

A From dentist Phill Stemmer, at the Teeth For Life Clinic: The worst drinks contain refined sugars (sucrose, fructose, glucose), which lead, in the presence of plaque (bacteria), to decay.

Many so-called "healthy" drinks have high acidity and can also damage teeth by dissolving them. Fruits can be acidic but are a very healthy snack, and so should be encouraged. But the best drink by far is water.
