Even with our best-laid plans, sometimes what we have planned for our teenagers and their development and their sex life is different from what actually occurs. The important thing to happen, if you find out that your child has entered sexual activity when you deem it to be too early, is to find out if they have enough knowledge to keep themselves safe. So the most important thing is, without being judgmental, you want to make sure that they're armed with all the adult information they need. They need to know how to protect themselves from STD. They need to know how to protect themselves or their partner from unwanted pregnancy. That aside, if you're hoping to change them and change their romantic path, the only influence, sadly, that you're going to have on a teenager is to change their peer group. Most sexual attitudes develop from a peer group. So sometimes it can be really inconvenient for parents - it may mean you need to move, it may mean you need to at least move schools, but if you really think that your child is on a track, that this negative behavior, that the sex is not linked to love, that it's not linked to commitment, that she's doing it because she has low self-esteem, that she's trying to get false attention from guys, then it is proper to intervene and protect and save your child.
