Why are gay guys so promiscuous
Homosexuality shows a reasonably high heritability. Research has found that lesbians are inclined toward even less promiscuous lives than heterosexual women. Researchers repeatedly find that.
A recent study found that over two million gay American men had not had any sex in the last five years. Still, it remains true that some gay men are profoundly promiscuous, but the numbers are smaller than some people think.
