Helen Beckman, 55, from London, runs a jewellery business. She is married to company boss Michael, 56, and they have two adult daughters. Helen says sex is great because she maintains the mystique...

I'VE never felt sexier than I do now - or enjoyed making love so much. When I was younger and a a full-time wasn't as relaxed about my body, or about sex.

My husband and I were much more worried about looking after our daughters than making love. But now they're grown up we don't have to worry about keeping the bedroom door closed.

My husband is the only lover I've had. No one discussed sex when I was younger - until 20 years ago I didn't even know what oral sex was. Luckily, I've never had to fake orgasms. If younger women do it's because they want to please their men. Women my age don't have that pressure.

And I don't feel I should be doing it five times a week any more - it's quality rather than quantity.

The longer you're with your partner the more you trust them, which leads to more experimentation.

I try to maintain some mystery in our marriage. I'd never wear old pyjamas to bed - I put on a sexy camisole. And although I've passed the menopause, taking HRT hasn't diminished my sex drive.

I've never been interested in sex toys and I can buy sexy underwear from lingerie shops. Joan Collins shows you can be alluring at any age - it's all about confidence and trust.
