My bf and I tried anal and it hurt like hell. I stopped him because it was so painful, and he didn't go in very far. (without lube). Okay, so now my rear is bleeding. No much, just a bit of spotting, a bit like when you've lost your virginity. My question is, should I be concerned that it's bleeding? The pain was unbearable, and I've been suspicious I might have hemmorhoids. Any advice?
