Many of us believe the older we get, the more sex fades away each year. At a young age, we're taught men sexually peak at 18, while women reach their sexual prime time in their 20s, but the truth is, the best sex of our lives is tied to self-confidence. In a study conducted by Natural Cycles, the world's first app to be certified as contraception, researchers found women experience their best orgasm at age 36.

The survey revealed orgasm, feelings of attractiveness, and most enjoyable sex all get better with age, specifically in women 36 and over. Women in their late 30s and above scored 10 percent above the average when it came to confidence and body image; about six out of 10 admitted to having the best, and greatest number of orgasms; and they scored 10 percent higher than the younger age group (23 and younger). About nine out of 10 women in the older age group reported enjoying sex over the last four weeks compared to seven out of 10 in the middle age group (23 to 36).

"Our findings show that although women over the age of 35 engage in sex less frequently than younger age groups, they actually tend to have more and better orgasms," wrote Natural cycles, in their blog.

The researchers surveyed 2,600 women using the standardized McCoy Female Sexuality Questionnaire methodology. This method was designed to measure aspects of female sexuality that are likely to be affected by changing sex hormone levels. Estrogen, progesterone, and testosterone play major roles in women's sex drive, with estrogen levels generally declining during perimenopause, eventually falling to a very low level.

The women were divided into three groups: younger, middle, and older, and were asked about various aspects of sexuality, like sexual attractiveness. While women in the older group scored higher than both groups, only four out of 10 women in the middle age group reported being happy with their appearance; seven out of 10 women under 23 said the same. Older women were more self confident about their sexual attractiveness and overall appearance.

When it came to climaxing, only five out of 10 in the younger groups of women had admitted to having more frequent and better orgasms. A little more than half of the youngest group agreed they had great sex over the last four weeks compared to their counterparts. The younger group seemed to be having the least enjoyable sex with limited to no orgasms.

As a whole, women gave mixed responses when it came to sex frequency. Under a third of women surveyed said they had sex twice a week, over one-fifth three times per week, and under one-fifth got intimate just once a week. Moreover, one in three women felt sex should last longer, while one in ten felt that it should be over quicker.

Overall, it seems the older women get, the more fulfilling their sex lives.

A 2016 study presented at the Annual Meeting of The North American Menopause Society in Orlando, Fla., found while women and their partners had lower libidos, these women had a better knowledge and understanding of their bodies, and how they work when it comes to sex. They also felt more comfortable in their skins and bodies. This ability led them to develop a higher self-confidence to express themselves sexually, and to communicate their needs to their partner.

Growing old doesn't mean your sex life is doomed; although the quantity of sex may be less, the quality only gets better.
