The fact that other athletes were so insecure as to berate you about your size speaks volumes about their poor attitudes. Outside the fetish and separate from the positive humiliation aspects, the people you work with should have enough respect for you and your abilities not to tease you about your size. I don't blame you one bit for wanting to leave pro sports, I just think it was immature for your teammates to disrespect you like that.
