I have no idea how to explain this... TW: SA

I've been terrified of having sex with a guy since, and in any case I know that I prefer women by far. For some reason I decided that it would help me get over things if I had a consensual experience with a guy, and I ended up having sex with this guy I know two days ago. It weirdly did help me feel better because i was able to give consent and to feel safe, but I still know that I prefer women. I think I want to do it again with this guy casually but I'm not at all used to the whole penis thing and I'm still rather sore from the other day and I was bleeding after. We didn't use protection and I'm not on birth control I'm really bad at keeping track of my cycle. It also turns out he's really into anal and I am well... not and I did try but I hated it and he stopped. Now we're still talking and he told me he wanted to do it again but I'm scared he won't want to because I wasn't good enough in bed or not attractive enough. Plus, he's in my class at uni and I'm nervous for when I have to see him again knowing everything we did. He has no idea any of my history except that I've had lesbian sex- and doesn't know he's the first guy I've had sex with. He's also totally not my usual type (even gender aside) and nobody knows what happened aside from a friend that lives in another country right now. 

Anyways, that's everything on my mind right now and I have absolutely no way of sorting through this on my own.
