the point is if you think you'd feel ashamed and wouldnt be able to live with yourself, you clearly arent comfortable with your own sexuality. Look, I wouldnt want to to go out and eat pussy, but if there was a reason to do it that benefits me enough, fuck yeah i'd do it, and not care about it - because i know i'm still gay.
Anybody who says they wouldnt do it basically saying they wouldnt do something moderately disgusting/uncomfortable (to them) for money - which i find really hard to believe - i can understand having some moral issue with somewhat prostituting yourself out, or not caring about the money, but otherwise, no dice
