Dark,
I completely agree with what you've said and it is consistent with my experience. However, what you're missing is the authority aspect. Males who are seeking counseling as well as HS males are rarely motivated to have sex because the woman is exercising her authority over them. They're (and me) just horn dogs. There are 2 HS teachers that, had they approached me, I'd still be smiling 30 years later!,-} Didn't happen tho'.
Girls, however, attach an emotional aspect. And the male teacher/coach/therapist plays on the authority/counselor/leader of the situation. Girls are rarely (although sometimes) motivated by sex, unlike the boys. Therefore, they are much more vulnerable and the abuse is much worse. I could go on, but my pizza just arrived!!! But Dark, note that you are right, but it's the abuse of authority that is the main theme, I would think. Have a good 4th!
I repeat once again: I ONLY addressed the attitudinal impact on boys/men in this situation. I specifically mentioned more than once that I was NOT talking about the ethical or moral view of it; I added to make it clearer that I would stop any such interaction happening that I knew about if it were happening to my kid, or a kid I knew.
Bringing in the whole power-figure aspect is beside the point in this specific discussion. People--men or women--who are authority figures shouldn't be abusing that trust, period.
