I think the advice you have gotten so far is great! waiting to have sex is soooo important. I was pregnant at 16 and it was not easy, my daughters father fed me all the lines that i wanted to hear. He loved me, we were gong to be a family etc. My daughter turns 12 today and he is long gone. I met a great guy when she was 3 years old and that great guy is now my husband and her dad. when your a teenager you think so differently than when your an adult. You sound very mature and know what you want...follow your dreams you can so do it all! children are a blessing but they should come after you have had time to grow yourself and are done with school etc. They cant live on love alone they need soooo much. enjoy your teenage years, make some good memories
as far as your boyfriend being "the one" hey you never know it could happen but remember if he is "the one" he will wait until your ready.
