No offense, but why do gay men like to dress up as women? Anon.
No offense, but generally we don't You're confusing homosexuals with transvestites, many of whom are actually heterosexual. When a man is both a homosexual and a transvestite (or cross-dresser), we call him a "drag queen." Drag queen culture is very colorful, which is why it seems so prominent in the gay scene. During Gay Pride parades and marches, the cameras will often zoom in on the drag queens and other colorful participants and ignore the more "ordinary" gay people. For the same reason the gay media often presents a disproportionate amount of cross-dresser portrayals in movies and documentaries. Some "drag queens" may be transsexuals who are in various stages of transitioning from (biological) male to female.
Drag queens are only a small percentage of the gay community although the media may make it seem as if most, if not all, gay men are drag queens. In truth, most gay men are very happy as men, have no real "identification" with females (as many drag queens do), and have no desire to dress up as women. Many feel the gay community would be quite a bit duller without its drag queens while some butch gay guys get awfully tired of the constant confusion between gays and transvestites.
