Help girl is obsessed with me and I think she d me!?

Ok Im 16 and I was at this party and everyone was all drunk but I only drank a beer or 2 so I was pretty much sober but all of a sudden this chick starts grinding on me and she is hot and all but she probly has STDS and is a major s1ut, shes already slept with half the guys at our school. I kinda backed away and she grabbed my hand and dragged me upstairs to her bedroom and started unzipping my pants and I was all like whoa whoa whoa whoa.......whoa gtfo off!!! and I tried to run back downstairs but she tripped me and got me on the ground with her on top of me. She pulled down my pants and she held me by the arms and basically had her way with me. I tried to get away but I literally couldn't, her whole body was on me and I couldn't get away! It hurt my pelvic region she was bouncing on me pretty hard I was really mad, I just ran away from the party back to my house I was so mortified! I want to press charges or something, Im really just scared for life now, I feel like a victim. I mean what was I supposed to do-hit her and be hated by the whole school and get arrested or let a hot chick do me. Now im afraid I have an STD because I didn't even have a condom and she probly didn't use birth control pills so I could be a dad! Im literally afraid of her, I shiver when I see her and try to avoid her. Next day at school, she slapped my and kept huggin me and crap like I was her boyfriend. I don't like her doing that, I like another girl not a diseased infested w**** that basically d me! She gave me her phone number and keeps calling me and has been ually haring me everyday at school since then. What do I do, she keeps ually haring me and grabbing my and stuff, I don't want to tell the teachers cuz ppl will find out and Ill look gay. I don't want to tell her to stop becuz she will tell everyone im gay! Im afraid that if the girl I like sees her doing that to me, I might not get a chance with her! Shes older-18 what do I do? Could she get charged with statuary ? Could I get like an anonymous restraining order or something or get home schooled?
