Its all just a part of growing up, but I was told when I first went to work back in the sixtys, that once you start having some real good sex they will go away, and yes they did, but a few bumps on your shaft wont hurt the girls will love them, just as they love ribbed condoms.
Good Luck
Hi,
Suppose they are ' Fordyce Spots ' , you could Google for more information. In any case, at your age, you should get all your health doubts confirmed from your doctor, may be next time when you have a physical, unless they start bothering you some way, in which case, you should immediately see a doctor.
