there's literally no market for it and the studio that did it inadvertently ruined one of their actors careers
Gay men wouldn't want to watch guys fuck women (unless the guy was really hot and the woman wasn't the main focus)
Bi guys might, but I don't think they'd appreciate the "gay cure" vibes it gives off knowing that the actors identify as Gay rather than Bi any more than a Gay guy would (the movie in question I'm refferencing straight up portrayed the scenario as a bunch of Gay guys suddenly being cured of their gayness)
and any straight girl who watches gay porn would probably want the guys to fuck each other, not almost fuck eachother in the first scene, see a girl, and then turn straight and gang-bang her and completely ignore eachother for the rest of the movie
also the actor in question (Blake Riley) Identified as gay and was strichtly a bottom, then starred in the "straight for pay" movie and started saying he wasn't gay anymore and wanted to fuck more women....so his boyfriend threatened to leave him and he decided to quit porn in order to save his crumbling relationship
