Believe it or not, this is actually a serious question. By the way, I'm a straight girl. I've watched a lot of porn and I generally like all 'regular' types (ie. not the stuff that starts to get out there such as bestiality). I noticed that in a lot of gay porn, one or more of the guys has really red necks and chests. I looked for the same thing in straight and bi porn and didn't see it anywhere near as prevalent. Does anyone know what/why this is? I don't get why it's just the gay porn - you'd think that sex is sex no matter who's getting what and from whom. Ever since it occurred to me it's been a burning question in my head, but since my closer guy friends are all straight afaik and the girls I know aren't really the gay-porn-watching types (not that they'll admit to me, anyway), I don't have anyone else to ask.
