Well if your parents aren't arguing about him, then that's awesome! As for parent's AGREEMENT, maybe you should introduce him soon, just so you can avoid them learning about him from someone else. That'd be extremely bad.
You shouldn't be dating anyway.. Do your parent know? If they do then that probably means that they don't mind. But You should definitely bring him to meet them so he can see daddy's gun before he sees daddy's girl. ;)
Meh I was dating and having fun before I was 16. It's not good or bad. Tell them. Whatever rhythm you get in now with telling your parents, you'll stick to for life. Mine is keep it simple. As long as he respects you and your boundaries and you never feel pressured to do anything- smoking, fun, etc. and no. My parents learnt to tone down their opinions but they still gave them- it means they care.
