In my personal opinion, probably wait till you turn 18. There might be lot of people out there who tell you its ok to do it as long as you use protection and things like that, or peer pressure might come from your group of friends who claim they have done it or how good it is etc etc. I would suggest please wait till you enter college, read up on all sorts of protection against pregnancy and avoiding STD's, know what you are doing and then get into it. Having responsible sex is more enjoyable, especially when you are an adult! Happy times to you!!
