ah, I feel for you.
I have been boy crazy since Pre-K. My first Boyfriend was when I was 4. I had a "boyfriend" pretty much all of elementary school. Thankfully by middle school I was fat and had acne, so although I had crushes on the boys, none of them like me (i'm sure it kept me out of A LOT of trouble). HS was pretty much the same. I lost weight and "prettied" up in college, and Ive settled down some.
My niece (who is 16) has always been boy crazy as I was early on. Unfortunately she didn't go through the fat, ugly phase and did get in trouble (sex at 14
).
My mom tried everything to deter my boy craziness, and nothing worked. Good Luck though!
