Completely open.
I'm as straight as straight can be.
I don't get pleasure out of my own pleasure unless it's directly connected to the pleasure of others. Ie. a handjob is interesting, but it does nothing to me. I think my last gf tried that until both her arms got tired. She gave up. But sex I like a lot because it's less about me getting pleasure and more about pleasing someone else. Seriously, seeing pleasure and ecstasy in someone's face is all I care about. What the fuck have I got? Male sexual pleasure sucks. I can have an orgasm with a straight face, what the fuck is up with that? That shouldn't be called an orgasm.
I don't think I have any fetishes that I'm aware of... but if my partner did I would probably go along with them.
I'll talk to my girlfriend about it if I want to; I can talk to me friends if I want to (I don't really), so yeah, I'm open. There's no reason to hide, it's just sex.
