For starters, fewer people consume gay porn, so gay porn studios, as a whole, can't be as deep-pocketed as their straight counterparts. You could ask yourself why these guys are in straight porn, since gay porn is reputed to 'pay better' to male performers, but I actually don't buy into that idea to begin with. Peter Pounder, who's himself straight or at least straight-leaning bi, said he knew of guys who perform in straight porn but actually prefer sex with guys. That 'the guys that shoot bi porn are actually only gay and str84pay' seems to be true, at least in some cases.
