The question to first answer with regard to Anal Sex on Frat Pad would be:
Who are they trying to market Frat Pad to?
I mean if they are trying to market to women, then that could be why there are no confirmed reports of Anal Sex.
Though if they are trying to market to the gay population then OMG they so need to go buy some condoms and have the guys fuck like crazy. I LOVE SEAN CODY VIDEOS!! I mean I know there only questionably straight and if they are straight then there only doing it for the $$$, but I love using my imagining imagining that they are like hot college football jocks or something, and they definitely do some pretty athletic positions, that I would someday LOVE to try out. I can dream that a sports team (football, baseball, wrestling, swimming, anything really) is going to get all horned up in the showers after a game and just get it on right.
