You’d be forgiven for assuming that your sex life peaks in your twenties. After all, these are often the carefree years of one-night stands, friends with benefits and first true loves.

But according to new research, the age women claim to have the best and most fulfilling sex is actually 36.

Commissioned by contraceptive app Natural Cycles, 2,600 women were asked about their experience of orgasms, feelings of attractiveness and how much the enjoyed sex.

Their answers were then analysed by age group - younger (below 23), middle (23-35) and older (36 and over).

When it comes to sexual attractiveness, women aged 36 and over proved to be the most confident in their skin with eight out of 10 saying they felt sexy.

However, only four out of 10 women in the middle group said they were happy with their appearance while seven out of 10 women under 23 said the same.

The older women also scored highest when it came to climaxing with nearly six out of 10 reporting more frequent and better orgasms.

In contrast, just five out of ten said the same in the younger groups of women.

Similarly, 86 per cent of the older age group said they had great sex over the last four weeks compared to 76 per cent in the middle group and just 56 per cent of the youngest.

When it comes to frequency, under a third of the women surveyed said they had sex twice a week, over one fifth three said times per week and under one fifth got intimate just once a week.
