pain during sex?

C.
Last night me and my boyfriend of 8 months had sex without a condom wasn't the first time going raw but for some reason it started burning, I had a yeast infection about a month ago but it's fully gone and it feels different. I don't think it was because I was dry I was actually pretty wet lol, but it hurt more after my boy came in me and he kept going, I don't remember it hurting before he came,What's going on?
