Personally as a guy, I would suggest that you both wait till your 18. I know it'll be a tad longer but hey, it'll save you guys some stress, and some arguments. Trust me. I've already had sex with one of my past exs. I regret it a lot now. You don't want that kind of regret stuck in your mind. Along with that, it was under aged sex and completely wrong of me to do so. Rob is correct. Talking it out with each other can be a great advantage to the both of you. What if he had a sexual disease that he doesn't want you to catch? What if he doesn't want you pregnant at the age of 16? Hope this helped in some way or the other.
