Tittle, let me tell you somethings...
First, one of my best friends is gay. He is one of the coolest guys you'd ever meet. Phenomenal guitarist, great singer, smart, conversational. Hell, if I was gay, this is the guy I'd want to go out with. I've been friends with him since we were six years old. He came out to me when he was 18. You never would've known he was gay, and still you'd never know unless he, or someone else told you. He's still one of my closest friends, and i've never felt awkward or trepidatious around him. And yes, I've seen plenty of movies with him. I even went and saw that sad, sad movie In And Out with him. Didn't make me feel uncomfortable at all. You know why? Because I'm secure with my sexuality as he is with his. And we both knew where each other stood.
Now personally, I think you have some deeper rooted issues you have to deal with. This is not the first time you brought up something "gay" on the forums. Maybe it's just part of growing up and you feeling you have to fit this macho male stereotype, but if it's more than that, trust me, find someone you can talk to about it. A therapist, a doctor, a teach you trust, just someone you can trust (just make sure it isn't a priest...)
