I'm with Jamesn and GG. Any time one man's cock touches another is one fucking time too many in straight porn. And how much man ass do I need to see in my stroke movies? Not that fucking much, lemme tell you.
DP isn't edgy. DP is the natural result of producers saying "Well, she's had one in her cunt and one in her ass, whaddawedonow huh?"
It's lazy porn and very, very festive

Edgy porn doesn't exist. It's all been done before and it's all just variations on a theme.
For the most part, male performers are life support machines for cocks. A huge section of the audience superimposes their face onto the male star's body so it's THEY who are fucking the porn girl. Not a male porner. That's why POV is always a popular genre.
But cocks rubbing against one another? "I think you've come to the wrong bar, sir"
