It doesn’t sound like the way you prefer to masturbate should be causing you any problems. The problem with the boys who lay on their stomachs is the amount of pressure they are exerting on their dicks – but there’s no way you could exert as much pressure using your forearms as these guys do using their whole bodies. So I would say that you don’t have anything to worry about here. :)
