So the other night I was really drunk and I brought a girl back to my place and I was too drunk for sex, I couldnt get a full errection. Still she was giving me hand job and all still I couldnt get any further. Two days later a woke up with a pretty sore foreskin like she had been pulling too far back or something, its sore a bit when it touches my trousers and when i go to the toilet. Do you think thats the reason or could it be something else?
