Can somebody help me? Going to high school next year.?

I'm 14 years old and going to be a freshman next school year. My grades are mostly A's and I already have a small job of babysitting. My life is pretty much planned out and I'm going in the right track except for one thing...boys. All the friends I have that I hang around are guys. So it's me, this one girl in a group of like at least 12 guys. Some are super protective of me, some are honestly just my friend, and still others are complete jack asses. I realized that if the protective few weren't their, there'd be nothing to stop the jack asses from raping me. I'm serious. Jeremy, Sylis, and Daniel (mainly Jeremy, but the other 2 help) are constantly trying to grab here, pull this off, pin me against a wall, fence, etc. Sometimes, they can be sweet and understanding, but it's usually just a front for something else. Dustin, Tanner, Kendrick, Tyrell, Jovanski, Ben, Josh, and Jason usually come to my rescue. And the rest neither help, or try to stop it. I mean, the jack asses are outnumbered 8 to 3, but they work together to get me alone. I think it started when I let them get away with too much. You know, it started innocent, a hug here or a kiss on the cheek. Then, the moaning & footsies started. Now, they hump me through my clothes & stick stuff up my legs & grab me in places they seriously shouldn't. I know it's my fault to let this escalate, but I didn't think anything of it. I'm kinda crazy at school & guys translate crazy into easy or loose. I stay around the protective ones usually, but like I said, the jack asses band together. High School is around the corner and I can't count on somebody to rescue me all the time. What am I suppose to do?
