I don't know. I'm marrying my girl. I guess it is part of the culture that thinks hook ups and all the sex you want and then if you feel like it you might settle down at 30 after having 10-35 sex partners.
If guys don't have to marry the girl they like to have sex than why have a relationship. The goal then turns to have sex with as many different girls as you can. Hook ups and cheap sex everywhere. Why settle on one girl.
That is just a sign of the times with the state of our culture and the birth control pill from the 60's and the sexual revolution.

Some people are just arseholes simply.
So live and learn, ALWAYS make sure you're both on the same page looking for the same thing.
