my story... please help.

so about a year ago i was almost raped by a 19 year old when i was 14. i got in the car with him because i thought we were getting food. he then continued to go park in a parking lot by my house. he made me kiss him and locked the car doors. i wouldnt but he forced my head to his face. he continued to push me into the back seat of where he tried to pull off my pants to try and have sex with him. i kicked him off and he hit his head on the door and i called him a pig he got off and drove me home. since then i haven't told anyone but i think about this time everyday. i don't know how to tell someone and get this guy in jail. advice?
