period sex

So I'm on my period and having mild cramps. My BF suggests we have sex. He said he doesn't mind the blood cause he thinks it'll be super wet and fun. But when he came and I got off of him, he got so scared of the blood on him. His expression was priceless! He was like "Ewww, OMG get off me hurry! Oh god it's dripping, no no no!!! Hurry!!" And he pushes me out of his way and dashes to the shower. I bring him his and my towel into the bathroom and notice the lights aren't on. He's like no don't turn them on until the blood is gone. Lol it was so funny:)
