Hey everyone im new and and just wanted to talk about my problem ive been having.. it seems like the head of my penis seems to be very sensative. This only seems to happen whe i touch it. it makes me feel uncomfortable and i can feel it in my testicles as well when the head is touched. ive had urine tests done about two weeks ago because i was having pain in my testicles and side of my body. they came back negative, everything was all good. but now it just really worrying me. i do mast urbate alot but idk if that would cause all this to happen. can anyone shed some light in all this plz...
