hi, i am a little embarrassed by this and would really like some help about a little problem i have been having for a few days now. It's a penis issue. I was having oral sex with my girl friend and she was a little rough. the following day i noticed, what appeared to be a enlarged vein or nerve below the head of my penis, to the right. it does not hurt. yesterday afternoon it seemed to have gone away but came back this morning when i woke up. i read a forum of someone having a similar problem and was told to put ice and go see a doctor if it persists. i put the ice and it seems to have gone down. it seems to re-appear in the morning when i wake up. any idea what it could be?
