I feel numb

I've had a great summer with lots of dating and taking control over my body and whom I want to share it with. But this weekend I went to see this guy that only used my body for his own pleasure and after I did my thing I had to leave. I feel so violated and so scared that people will tell me it's my fault. I shouldn't have acted so slutty. I feel so disgusted and sad. I've been used before but this is different.... dont know why and I don't know what to do...
