Personally regardless of gender I like strong main characters. Not spunky, I hate spunky, because I've never read a spunky character that can back it up. I like main characters who don't bitch about everything, if they don't like something, they handle it with maturity, or if they're younger they grit their teeth and bare it (there are some exceptions of course, like if they bitch in a hilarious way I love them for it) I also like characters who take things well. Even if they have weak constitutions they don't turn everything into THE BIGGEST DRAMA THAT EVER HAPPENED IN THE HISTORY OF EVER GASP. Weak or dramatic characters make me uncomfortable and embarrassed for them, if not wanting to just shoot them in the head.
Though to be honest, you made me like a man that was admittedly a faggot in mannerisms. That's tough to do so I have confidence in your ability to make any character awesome.
As for relationships, I like cute ones. Ones that start as friendships, where they get to know each other and are all cute together. (I'm such a hypocrite XD;;; ) but I'll read just about any kind of relationship. Hope that helps somewhat ^^
