Hi, My Boyfriend And I Were Aboutto Get Intimate Last

Hi, my boyfriend and i were aboutto get intimate last night, an he started fingering me, to the point when i saw lots of blood on his hands afterward, an started freaking out. I bleed alot. Im thinking by him doing that, he has sharp nails,long hands an was doing it very hard. Im thinking that i may have a bad cut. I have to literally hold my breath wheen i go to the rest room. It hurts very bad. How can i treat it, an how long do it takes to heal so that way we can get back to being intimate again?
