The reason behind guys playing female characters is often 'I don't want to look at a guys bottom' but honestly I really don't understand the reasoning. I mean I am a gay guy and as such don't particularly enjoy ogling womens bottoms but that in no way transcends into virtual worlds and dictates my decision regarding character genders in video games. Saying 'I am uncomfortable looking at the pixelated bottom of a member of the same sex' just seems like sexual insecurity. Also why are you looking at your characters bum anyway?
