Secrets of great sex at all ages

Loved crazy positions in your twenties, tried dress-up in your thirties and joined the mile-high club in your forties?

Then you are not alone. On our sexual journeys, the majority of us will try out different turn-ons in the quest for a perfect sex life through the ages.

And, according to sexpert Tracey Cox, our beside manner trends are pretty standard all over the country.

Here, we look at her findings on sex at different stages of our lives, taken from the bestselling book, Sextasy. He can't stop thinking about sex

Eighty-five per cent of 20- to 30-year-old men think about sex every couple of hours.

She's had same-sex fantasies or been bi-curious. Imagining what it would be like to make love to another woman is nearly always one of the top three female fantasies.

Statistically only 4 per cent of women tick the 'had a lesbian experience' box in surveys but in my experience, it's way, way higher than that.

There's plenty of incentive: A 2006 study of nearly 2000 people discovered that 76 per cent of women who slept with women reached orgasm (for women with men, you are pushing it at 50 per cent).

Lesbians are also the least promiscuous group and consistently report the highest sexual satisfaction.

Almost everyone's tried 'The Wheelbarrow'

This is the age and stage where most of us experiment with positions - the more athletic and bonkers - the better!

About one in 10 people have had a threesome And most of you did it in your early twenties.

Threesomes and moresomes aren't quite as common as you think.

The majority of people who've had them try them once or twice, then go back to one-on-one sex.

The less you know the people involved, the more likely you are to see it as a positive experience. It's also likely that you'll visit a strip club or lapdancing club - with your friends but increasingly often with your partner - at some point in your 20s.

Almost all of you have had sex outside

A throwback from our teens - when we did most of our sexual experimentation behind the bike shed, in the bushes, or in the back of a car - most of us will have sex somewhere semi-public in our thirties.

Under the cover of darkness in a park, on a beach, or in your own garden are the top choices.

Sex in the shower and sex in a hot tub is also popular.

Some of you will try bondage, blindfolds and spanking

Around 20 per cent of thirty-year-olds spice up their sex life with this kind of thing in your thirties

Either you or your partner have had your hands tied together to a chair or four-poster bed on a dirty weekend away.

Lots will continue to enjoy tying each other up but only 5 to 10 per cent of the population will go on to more serious S&M.
