I like straight porn. Some of my favorite porn actors are men who only do straight porn. I'm not sure what it is about it. Maybe it's because I love straight men. Maybe it's because the guys are sexier. Maybe it's because there are certain actions which make me quiver, that I just don't see in gay porn.
I think... it has to do with my mindset. When I'm feeling especially dominant and macho, I prefer gay porn. I want to see some sexy little twink get ripped in half and moan like a good little slut. When I'm feeling more passive or submissive, though, I prefer straight porn. I like being able to put myself into her place and having a guy who I view as more macho than I am make me quiver.
