My daughter keeps having sex with random guys. I sometimes wish she hadn't learned about sex at all.
Do you think that would have prevented her from having sex?
Why wouldn't I care about this? She's my daughter!
I know it seems bad to you, but it's her life and she is free to do as she wishes.
I mean, I don't expect her to be a virgin, but sleeping with lots of random guys is bad.
There is nothing wrong with sleeping with other people and even though she's your daughter and it upsets you. There is nothing wrong with it and you can't do anything about it.
