i went to my girls house to visit her, after a while things heated up and what ever, im not trying to brag about sex i actually have a question. as i was having sex i noticed on my shaft of my penis about half way down a spot appeared which wasnt there before i went, it kinda looked like a blood blister on my penis . i woke up and checked it again this morning and its still there but lighter in color. is it possible i might have pinched it and caused it. i have been checked 3 times, all said i was clean. another question. later that night i was trying to have sex again, she wanted it i wanted it but her vagina tightened up ALOT, like to the point where i couldnt even put in one finger. if anyone knows what the fuck was going on please put some light on this situation.
