Really?
Of course if you're hooking up with an ugly guy not familiar to hygiene rimming can be disgusting. But that's why you get to choose. Rimming is cool I don't know why would gay people find it unattractive. I've never even during suprise sex stumbled upon some unpleasant stuff while doing it. Really not a single time. But I get that "I can't kiss a guy who just rimmed me" thing. I don't like it too ; / It's funny cause rimming the other guy is cool with me but kissing the guy who ate my asshole is not. Doesn't make sense but from what I know I'm not the only one finding it weird.
But I like straight porn sometimes. Mostly because I just like straight guys. I was always attracted to that straight gene or factor xd and some times there are just hot guys and I want to watch them have sex. I like also those amateur movies with big bodybuilders fucking. Well you can't have them doing a gay porn so you can at least watch them fuck the pussy. And with women you can see much bigger size difference + straight sex is almost always bareback nowadays and the dick slides much easier into the pussy and you have better penetration sometimes. But those are the only reasons. I just like seeing big bulls in action. Eating pussy ? Fuck no. Disgusting. Sorry guys, not my cup of tea.
