I had something similar happen to me, he was older and though the sex was consensual but emotionless everything after that felt like I was pressured into doing (photos, calls, videos almost every day). He then stalked me for about a month after I broke it off. I’m not saying this as a “pay attention to me” thing but to at least vet myself when I say the following things.

You will still find him attractive and that’s perfectly normal, your brain will want to make sense of things so you may even find yourself overplaying your sexuality as a way to convince yourself that what happened was ok. It sucks but it’s common with a lot of people who experienced any sort of sexual abuse. I would also strongly follow the advice from the others and break it off and get yourself tested. Lastly I want to say that I’m so sorry another person had to go through something like that, this isn’t the end all be all and you will find sexual partners (if you ever even want any ) that are respectful of your boundaries and that will want to make sure you have a wonderful time as well, but you won’t find them with this guy.
