A sexologist has said that around the age of 18, a man's testicles produce the most sex-revving testosterone they ever will.
But it takes about 10 years after the peak output to reach a man's maximum testosterone levels, which means that a man's sexual desire does not spike until he attains the age of 30, Fox News reported.
Ava Cadell, Ph.D., a Los Angeles sexologist and founder of LoveologyUniversity.com, said that it is around 30 years old that women achieve their orgasms with more ease than they will at any other age.
