Had sex and feel uncomfortable

I was raped a year ago(January 2017) and sexually harassed and threatened this (January 2018) year, and I haven’t had sex since I was threatened. Last night I had sex with a guy I had just met and he was really nice and the sex was decent for him and uncomfortable for me. We cuddled for the rest of the night and it was okay I didn’t feel scared, but I’ve felt gross and dirty and uncomfortable since it happened. I don’t know what to do because I hate this feeling and it makes me never want to have sex again.

I’d love advice if anyone can give any
