Dear MIRIAM: Biker's son gets me so revved up; LETTER OF THE DAY.

Byline: Dr MIRIAM STOPPARD

Dear Miriam I'VE been going out with a divorced man for a few months. He's 55, and I'm 30.

He's a mechanic and we met through our mutual passion for classic motorbikes. We have many other interests in common like heavy metal music and rock 'n' roll and we love the outdoor life.

Sex with him is OK but sometimes his age is against him and I'm often left feeling frustrated when he can't bring me to orgasm.

I met his 26-year-old son a few weeks ago and there was an instant attraction. His son made it obvious what he was after and I couldn't resist. We ended up having sex on the sofa while his dad was asleep upstairs. It was fantastic.

What is the best way to break up with my boyfriend so I can go out with his son?

IT'S hard to decide which of you is more contemptible. Him for betraying his dad or you for being such a willing accomplice.

Maybe you're attracted to him because he's a younger version of your partner, who could have given you more sexual satisfaction 30 years ago?

But they're not the same people. If you stopped being so sex-fixated for a moment, surely you would see there isn't a very nice person lurking underneath the son's persona? He's selfish and sly.

If you continue to give in to your lust you will create more problems than you can handle and it will be your own fault.

Do you really want to bring chaos to your partner's life and rip apart his family? At least leave him with some semblance of family unity and self respect.

If any good has come out of this situation, it is that you now know your feelings for your partner are lukewarm.

You can still emerge from this with some integrity. Your partner deserves better than you, so end the relationship before he discovers your sordid secret.

Leaving these two alone will put you in the best position to meet someone who can tick all your boxes while keeping your self respect.
