I know what you’re thinking “nobody wants to see my ass” or maybe it’s more like “I don’t want to see another dudes ass, so why would I put mine up there?” Whatever the reason you forget that most of the audience here is female. Yes, most of them do want to see it. Remember that females are actually attracted to the male body for some messed up reason. :)
