Was I raped?

This has been on my mind lot lately. And a little in my dreams. In high school I was raped at a party. After he raped me, another guy came in and said "I can't believe I'm about to have sex with a 16 yr old". He was 22. I can't remember anything after he said that... do I just assumed he raped me? I'm 21 now and it just started bothering me these last few months out of the blue
