Bleeding when fingered

jessica
So me and my girlfriend have been having sex for over a year and every time she fingers me i bleed. I like it hard but she doesn't scratch or anything and i find it normal now but Im wondering if anyone else has this issue or has it happen to them. I am wet so from my understanding it cant be that there's unwanted friction and my Cherrie has definitely been popped. And i dont feel pleasure unless its hard. It doesnt hurt at all while she is fingering me and when she pulls out is when we see the blood mixed with my juices. Any ideas or comments to help me understand whats wrong with my body?
