Hey! Thats happened to me too! Rather embarrassing when he asks me "are you on your rag?!" and then seeing blodd allllll over his fingers.. I shot outta bed really damn fast I can tell ya.. And I still don't know why I was bleeding.. Soo if anyone does have an idea, that would be super! Hah

I had that happen to me once. I wasn't on my period but I bled when he put his fingers in me. Turns out his nails were too long and he accidentally scraped me inside. I think that may be an issue with your guy. Check out his nails and have him trim and file them before doing anything to you. You don't want to have scrapes on the inside that are prone to infections. Most guys won't mind if you explain the situation. They should be grateful to know that they can actually make it better.

Hope it works!!
