It got a little rough...

My FWB and I really enjoy rough sex every now and then. I had just finished my period completely, but the sex was so rough that I ended up bleeding quite a bit after it was over. This morning the bleeding has subsided so I'm not that worried. I'm a little sore but no real pain. This has happened a few times before but he is a BIG guy, so I kinda feel like its not completely abnormal.. Thoughts?
