Sexuality Question

I'm a straight male, at least I think. I find women attractive, and want to have a girlfriend. Something just doesn't feel right though. The male body, (face, muscles, abs, legs, etc NOT genitalia) is attractive to me. Like sometimes I'll see a picture of a guy with a nice chiseled face, body, whatever. And I'll think "Holy shit that's sexy!" But even the slightest thought of dating another male, or having sex with one is absolutely repulsive. Whenever I watch porn, I automatically get turned off whenever I see gay porn on thumbnails or ads. I get no thoughts or urges to snuggle up, or touch/be close with other guys. No offense to the gays, and I fully respect and support that. Is this normal? Or are there a lot of people that feel this way? Thanks!
