the urge to have sex is very normal. when i was 11 i started masturbating 3-6 times a day which helps control some of the urges. it is very smart to wait, but remember that if you decide not to or your urges get the best of you, be SAFE. use protection; you aren't ready for a kid.
I just saw your post to the young girl who wants to have sex, you seem smart and like you know what you are talking about. Take your own advice. Wait to have sex.
It's normal to feel this way, but you should wait to have sex. You are young, and like you said too young to raise a baby. If you're really aroused that often, you could try masturbation. It might give you the satisfaction you want, and you're not risking disease or pregnancy.
