Men do not want to have sex more often than women.
Well basically you're dead wrong.
There's three pages of information on WebMD but this summarizes it well enough -
"Men want sex more often than women at the start of a relationship, in the middle of it, and after many years of it," Baumeister concludes after reviewing several surveys of men and women. This isn't just true of heterosexuals, he reports: gay men also have higher frequency of sex than lesbians at all stages of the relationship. Men also say they want more sex partners in their lifetime, and are more interested in casual sex.
Edit: That's why I said you are a very naive person regarding this claim.
