So my boyfriend fingered me and he has done it before a lot but the last 3 times he has gotten really really rough and it feels good! But whenever he takes his fingers out it is always bloody, so the past 3 times it’s been bloody, and like 30 minutes it was bloody again, I had my period September 9th-13th. So today is the 20th and I’m bleeding lightly from him fingering me. He goes for my g spot and everything so he is very rough... but I’m starting to get worried. This isn’t usually normal for me. It’s only when he fingers me tho, when we have sex it’s fine but just fingering... any advice??
