I feel like there are some GAGers who know just a little too much about the opposite gender to be the gender they actually claim to be. It's as if they know first hand about the specifics. Also, the "girls" who ask questions like, "Would a guy like it if I (insert some random fetish)? ;)" seem suspect to me.
I've been seeing soooooooooooo many girls who are guys lately. It's INSANE. Like who do they think they're fooling? Oh! I do know one girl was posting as a guy since she thought we wouldn't realize it was her XD
