Good question!
He has good wholesome lady friends and finds the easy open sex to be just as strange as I do however he’s also a 21 year old guy who isn’t going to turn it down either. One of his best friends that he spends a lot of time with is a non-promiscuous young lady.
When I was a teen, my Mom said this... “men sow their oats with some women but they marry the other kind of woman”. I am not sure if this still applies. I am wondering if young men still have a higher standard with respect to the woman they fall in love with and want to marry (not just spend 20 minutes with). If not, I would predict divorces to even rise more.
