You don't have to be super manly for gay guys to like you, in fact "twinks" are very popular in some circles. I think you and I have the same problem, and it's that we don't have very many queer friends (in real life). Even though we're in relationships, it's nice to feel a little "verification", if you know what I mean. Problem is, the guys we hang around are straight and we are not. So of course they're going to find the pretty girls more attractive than us, because we aren't girls! Whenever I ask guys what would make me more attractive, they usually say things like, "More make-up, longer hair"... very feminine traits. We've got to find ourselves some gay guys!
