what is it?

Yesterday my boyfriend and I had sex on my period, no condom, no nothing. This is the reason why, We went to get my nails done and as I was sitting in the chair, he just couldn't stop Staring at me. He said  "babe we have to today😫 idk what it is but ugh being around you when your on your period makes me want you more." I told him no bc I'm on my cycle to just wait till saturday.  That didn't happen.  Sometimes I think my boyfriends a metaphorical dog 🐶 😂 but it was amazing so I guess it was ok
