bleeding after fingering

Rachel
Ok guys, I need your help. So my boyfriend fingered me on Sunday night before intercourse but for the first time I bleed, we realised after that his nails were sharp because he'd been biting them so we think he has cut something, he went really deep and rough and hit the spot. So do you think he may have cut it or what? I need help! Bleeding stopped on Sunday night straight after and bleeding was very bright red. Although today my uthera has been real sore. I don't have an infection I know that!
