That one guy named after a philosopher

So... I told this to one person and... I guess this is my second time saying this not in my head...

Just um. Trigger warning

I was at a camp with friends, and I met this really really nice guy. We became friends really quickly and kept hanging out together. (At this point I know him 6 hours) in the evening there was this band playing, and he invited me to go watch a movie on my phone outside, alone. He chose the movie (so he's holding my phone) and it turned out to be really explicit. During the first sex scene I got really uncomfortable and suggested we switch movies, he told me I was being childish and uncool. Being the naive 14 year old I stayed quiet. He started asking me very explicit questions, and the questions got to my sexuality, I told him I was asexual. He said he could change that. I... i won't go into details what happened, but I had bruises on the inside of my thighs, chest and neck. And I'm so ashamed... I froze... I didn't do anything. I ended up telling a counselor only about the questions, and he got sent home. But I was outcasted, and the questions I got asked just make me sick. "Are you sure you didn't enjoy it?""why didnt you say stop" "you were probably sending out signals" AND THEY DIDN'T EVEN KNOW THE WHOLE STORY. He harrassed me for months by phone, and if i blocked one account/number he'd use another. I was so scared. He finally left me alone. But I'm still scared, and i don't have anyone i can talk to... I don't know what to do...
