Well most guys can get away with standard DP (anal/vaginal) without worrying too much about the implications, cuz you know, there is that wall of tissue (albeit thin) and the dicks are in two different holes. It's in straight porn all the time because I'm guessing, most likely, that the majority of the guys aren't pussy homophobes and are confident enough in their sexuality that if that dirty slut wants to be double stuffed, then by god, she's gonna fucking get double stuffed. That's just taking one for the team all for the greater good.....defiling a kinky slut being the greater good. Now, it takes a real man to do double vaginal strictly upon the slut's request. Any straight guy that rubs swords with another guy just to please some dirty slut is either a sub or he has amazing mental fortitude.........but in any other scenario, well....that shit is just straight up enjoying rubbing your cock against another. DP is pretty awesome, but the totally bisexual nature of DV is kinkier, therefore more awesome. So yeah, I guess I DO like that shit.....not that I've ever done either, yet.
