Oy. I wouldn't have a tight leash. 15 is too soon to date but he'll look around at his peers in hs and decide it ok to sneak. I'd rather have my kid be open and honest with me than to be afraid of punishment, not say anything, and do it anyway. I'd keep a light leash on him and make it so he feels comfortable talking to you and getting advice from you, without any threats or anger. Works much better than trying to tight leash on him, grounding him, punishing him, etc. If he sees you as a concerned friend as well as a dad, you'll get further with him.
There is no possible way for him to "sneak" around and do it behind my back. No possible way in hell. I know where and what my son is doing every second. I am blessed with a GREAT kid too. He does not run the streets or anything like that. In fact, I have never even had to tell my kid he has curfew.
We have a great relationship and can talk about ANYTHING. He did come home and tell me the girl on the bus wants to blow him after all.
Nope. He is not allowed to date until after high school. He already has some chick after him too. He came home last year telling me this chick that rides his bus said she wants to go out with him and give him a BJ. Little tramp.
