Is it normal?

I recently had sex with my boyfriend, and things were great! It was a little rough, but we both enjoyed every moment of it and we were satisfied. He went down on me, and was a little rougher than usual. When I went to the bathroom, I noticed I had 2-3 bruises on my inner labia. Nothing major, but I saw a few. Is it normal for it to bruise like that and will it go away? This was very recent too (last night lol). I know he wouldn’t give me anything either, so I know it’s nothing like that. But does this happen to people or am I just a rare case?
