I was 15 and lost my virginity to my 14 year old girlfriend and she was more physically developed than me. She looks the exact same now and started her period when she was 11. Hell, she probably started puberty 2 years before I did

.
Truth be told men are just uncomfortable coming to the realization that girls are allowed to be sexual beings like their counterparts.
And honestly, if I had kids who were high schoolers banging their teachers I'd be pissed if it were my daughter and confused if it were my son so I'm not trying to be a hypocrite here
