I know... it just seems to me that if he was expecting a cheerleader and in the dark he grabs someone who is about 100 lbs heavier than he was expecting, it would only take a second or two to think “Hm, something is wrong here.”
They get stunned, like an inexperienced girl who is finding herself in that situation. Boys are drilled not to be violent and aggressive - especially to a woman and teacher. I was taught to avoid and to fight a rapist by my dad but most girls I hung out with would not have known what to do.
Boys are not taught to associate sex with agression and violence in relation to themselves the way girls are. But now that adults into sexualizing kids and focusing on them as an object of their perversions, especially boys with the homo thing, boys have to be warned about sexual aggression from peers and adults like good parents do with girls.
