IM SO EMBARRASSED

So, me and my boyfriendexnotexbeenfuckingwitheachotheralmostayearnowbutbrokeupsomemonthsago were having sex and it was good, we start to switch positions he looks down and is covered in blood. I'm so embarrassed. My period stopped already and I just bled all over him. I don't want him to touch me. Btw...this just happened. He's laying next to me.
