Well from experience, I find that women are generally more comfortable with their sexualities than most guys are. A general assumption but I think it takes longer for a guy to come out of a closet than a woman - and that's coz it's more widely accepted especially by guys, if women are gay/bisexual. Again a general assumption based on experience.
So I'd say that while most guys using this site are now outed / in the process of outing themselves, you do see a lot of newbies that sign up are gay males asking for advice on the subject
