Dear Yvonne, Are men more interested in sex than women? -Manny

Dear Manny, Though this is the general thought, it's not the general rule, as many women would contest. The idea that men have a stronger sex drive and more sexual interest than women is largely due to society traditionally having been more permission-giving with the male libido and pursuits. The true difference lies in when the sexes are interested in sex.

A woman's sex drive is related to her menstrual cycle. For many women, it's heightened during ovulation whereas for others it's the week she's menstruating. For males, his sex drive varies more daily versus monthly, and is dependent upon testosterone levels. A male's testosterone levels tend to be highest in the morning.
