is this normal?

Each time my boyfriend fingers me I end up bleeding! He said he doesn't mind it, however I think it's somewhat embarrassing and not cute at all!!! It doesn't hurt during, just somehow I always end up bleeding! Any ideas as too what's going on? I thought maybe because he's got very large hands and is the tallest guy I've ever been with, or maybe he's too rough? I just wanna hear some suggestions before calling the doctor! 😊
