No downside at all. There is a lot of people dying to watch these premature cummers. So hotThese guys were usually told to refrain from cumming for several days mainly to build up a big money shot. I don’t think they intend for the guys to cum easily. Because they pay for the shooting sessions, of course they want more footage/content for that money. That’s why you sometimes see them asking guys if they can cum again. Downside of abstinence? some guys can get too sensitive.
