They already threw out a homosexual super hero. He's called "Dead Pool".
They made up for the ick factor by making him hilariously funny, ala Paul Lynde, or Jim Parsons.
They also don't make him blatantly homosexual. He isn't pushing it in people's faces. He just keeps insinuating it.
Deadpool is rocking Morena Baccarin, who is the polar opposite of male.
Deadpool did squeeze Colossus’ buns in DP2, but only because Colossus is a highly moralistic Russian dude.
DP2 was good. Funny. They shouldn’t have killed Vanessa, because she’s way too hot to die.
Again, the LBGT thing came in with the two X-men females who were dating. One’s a butch sort of type, but highly cute, and the other a ‘Hello Kitty’ type Asian girl.
It’s VERY hard to infer any homosexuality out of Deadpool’s character as they are writing him right now.
