What is the peak age for a woman?

Society has held that when a woman reaches her mid-30s, she reaches her sexual peak, and her desire will decrease with each passing year after that. There are many factors that directly affect a woman's sexual desire, but current research suggests that age isn't always one of them. OKCupid also reported that as a man ages, he seeks out relatively younger and younger women, while his acceptable upper age limit hovers just above his own age.
