It hasn't been that long ago that I was a teenager myself. I do believe that rules should be applied and I've talked to my teenage daughter about sex, what the consequences can lead to if she decides to have sex, and most importantly safe sex. I know just because I say, "no, I don't want you to." doesn't guarantee that she won't and I can't be with her at all times. I was sexually active at 14 and had her at 15. I don't want that for her. Her daddy wants to lock her down to prevent her going through the motions that he and I did, but I've told him that isn't the way to go about it. I have a friend that has two teenage daughters. When we met a few years back they were 16 and 15. She had her daughters at the ages of 16 and17. Her mother asked her one day if the girls were having sex and she said that she didn't know because she didn't want to know. One day shortly afterward her youngest started telling her about one of her friends having sex. The friend had asked her mama if she could get on birth control and her mama said "no" because she thought it would be like saying it was ok for her to do it. So after she finished the story my friend asked her daughter, "Well, while we're on the subject are you having sex?" She told her "yes" and she then asked the older daughter who also said "yes". She immediately made an appointment to get them birth control pills. They are now 19 and 18 and still without any babies. I think when it comes to teens the word is "prevention" in referrence not only to sex but issues like smoking, drugs, alcohol, and violence. I think 15 is as fair as I can get when it comes to dating.
