PM caters to an audience with a specific fetish so not all, maybe most people would actually not get it. It's to try and get the most beautiful, straight young men with incredible physiques in their prime, guys who are not likely to get into porn, especially gay (at least prior to being on PM), to get them to pose as naked as possible, to show a much as they can of their bodies that they are never gonna show to anybody except their GFs or wives (i.e. ass hole) and to do as much sexual stuff that they can get away with (e.g. getting an unexpected hard-on AND PRECUM from Peter's touching). if you just want them to just come in like with a regular porn company without any pretenses and being upfront, I guess there's Sean Cody, Corbin Fisher, Gay Hoopla and Hot Guys Fuck for you. But where's the challenge in that? You are also not likely to get guys you will never see anywhere else naked because if they're willing to do porn, they are not the target of the PM fetish. And you'll never get guys who have ambitions of becoming pro athletes, serious fitness competitions and modeling, acting and careers as influencers on social media with product endorsements or even regular career paths as professional fields, those with large Instagram followings (the more famous they are, the less likely they'll do porn or even full frontal nudity), etc.
Of course, the appearance of OF on the scene has completely upended and complicated all of those things I just discussed LOL and suddenly all the guys AAG and PM have been trying to get naked on cam are now not just being nude but performing all sorts of sexual acts even on video lol, but still....you get my point.
