I am a twenty-six-year-old man and I wholeheartedly agree with your analysis on Fascinated with Women's Butts.

However, I wish you further emphasized the fact that this man needs to make sure his fantasy remains only a fantasy, and that he does not start pinching or touching the butts of those who do not consent.

I am afraid that unless he gets psychological help, he could wind up in trouble. I wish that you had emphasized this more.

I don't think it is relevant whether his fantasy is "normal" or not; I think what matters is whether his fantasy could put himself and victims in potential danger.
