I'm afraid that I'm more likely to give injury than to receive it.
Third time I ever got lucky, I put the girl in the ER with a bruised and bleeding c****x. She didn't even tell me she was hurt. Neither of us were experienced enought to know you couldn't hit it that hard. I found out about it from her friends, she wouldn't talk to me. I was 19, and I think I was scarred for life by the experience.
