it's so cool to see "straight" guys have their dicks touching
There's a good bit of that in so-called "gonzo" straight porn, which typically involves rough gang-bang scenarios. The woman has two or three large cocks in her mouth, and they can't help but touch whilst she's doing this. Two men will be facing each other as she strokes and mouths their cocks, and their cockheads will end up touching and rubbing together. Also, when the men line up for DP, their cocks sometimes touch inadvertently. Or, if the cock slips out in DP or the bloke
s, sometimes the cock will drag on the other guy's nuts or he'll sperm the guy's body someplace.
A fair number of straight porn stars won't do any scenes involving more than one male participant because they fear it's too gay. In straight porn discussion forums, there's always endless discussion about scenes involving two or males being "too gay" if there's any male/male contact in the slightest. They freak out if the woman does something as simple as put her finger in the guy's asshole while sucking him off. They react like little girls seeing spiders when a scene has double-anal or double-vaginal penetration.
I always find it amusing that the "straight" porn consumer doesn't mind watching an enormous cock in action for hours on end, going into a girl's ass. Now how close to gay porn is that? They think it's "straight" but how many real women want a ten-inch cock piston-pumping their assholes?
