Ive been having an issue, i masterbate alot maybe 2 or 3 times a day and i recently had done it one night for the 3rd time and before i ejaculated it felt like someone stabbed me with a needle right under the head of my penis and ever since (the next day {today} ) when i grab, pee, or tap my penis the same spot stings for about 10 seconds, i am a virgin i have not had sex and i am 18 and really embarresed if i have to notify gaurdian or doctor
