Why Do Kids Have Sex So Young Now?

Idk why it's probably because some parents treat there children like they are little kids and they wanna prove to there parents that they are adults so they act matures and since the kids already have boyfriends and girlfriends that when they have the chance to have s3x they do it because they think they are very responsible. I'm 13 and still a virgin and I know little 10 year olds doing it already
