Women's Hormones Cause Them to Reach Their Sexual Peak at 35
Considering that women's fertility decreases 3 to 5 percent per year after age 30, and at a faster rate after 40, this popular stat makes sense. Perhaps women are reacting to an evolutionary signal to get busy and have a baby. But this number originated in the mid-20th-century research of sex expert Alfred Kinsey, who found that women had more orgasms in their 30s than at any other time in their lives. Subsequent studies haven't been able to definitively prove that women are experiencing a surge of hormones at this age (like men do at when they sexually peak in their late teens), and many experts believe that the real reason women have more fulfilling sex in their mid-30s is because they're more comfortable with their bodies, so they're better able to relax and let go during sex, which primes them for orgasm—and in turn, increases desire. And let's face it: For every woman who believes she's in her prime at 35, there's a new mom who thinks her friskiest days were in her mid-20s, and another, remarried at 45, who's saying she's having the best sex of her life.
