What percentage of mexican men are bisexual?

First of all, Mexicans are no more (or less) likely to be gay than any other nationality.

Second, it depends on what you mean by "gay". In some cultures, only the guy who gets penetrated is considered gay. The guy doing the penetrating is considered straight, even if he only has sex with guys. According to the Kinsey Report, about 30 percent of males have had at least one homosexual experience to orgasm. So how many homosexual experiences does a person have to have before they're considered "gay"?
