bleeding and painful urination after being fingered

Hey, so I'm 19 and today my guy and I were messing around and he fingered me, it hurt which I wasn't sure why because I'm not a virgin (not experienced either tho) but the pain went away as I told him what to do but afterwards I went to the bathroom and I was bleeding a bit and now it hurts when i urinate, he has no nails so I don't know what this could be from. It's not my period because that was 2 weeks ago. Please help I'm really embarrassed and don't know what to do.
