Well here's the thing.... what church, school, after school program, extracurricular activity, aunt, uncle, mom or dad is going to tell teenage and young boys........"be dominant with that little girl".....none.
I don't mean in a sexual way, I mean in basic interactions, boys are taught to be nice to girls, because we are the physically stronger sex. There is explicit gender differences that boys and girls are taught to adhere.
SUDDENLY puberty shows up and high school and college and early 20 something appears and all that "be nice" stuff goes out the window and the socialized mantra is to be an adult with "confidence", but also "aggressiveness" with women yoi are interested in dating.
So you are talking about a literal re-socialization.... You can even argue it's like a wild animal aka young testosterone. finally able to be independent, and it takes time for some makes to reengineer their brains to this particular social outlook. This is American context, but appears in different degrees among most cultures.
