I think it's that she doesn't think she should be the President—and thus the "face" of the club—because she's transgender and Kinda Weird with her open sexual references. "Rather than someone like me", and all. I think she has self-esteem issues and was expecting some kind of castigation instead of light chiding, suddenly pushing for the bad thing she 'knew' was going to come eventually, to get it over with. And then it didn't come, and just left her stewing with her own nasty thoughts, without the perverse catharsis of it 'finally' happening.
That's my read of it, at least.
