Two days ago I noticed a small, about 3mm in diameter and about 2mm in hight, on the shaft of my penis. When it is pressed it hurts slightly, much like a pimple would. It is slightly red, which is the only thing that makes it noticable. I am a male, 16 year old virgin and I am wondering what this pimple like bump would be caused by. I have done a bit of research and I have found that it is possible to get pimples anywhere on your body, including your genital area. I have also read a bit about ingrown hairs, so that is another possiblity.
However I have read about servral std's that involve pimple like bumps. I highly doubt it is an std, all I have only had oral sex once and the girl I did it with was a virgin.
Also I play hockey, so I was wondering if it may have been caused by sweat. I have told my mother about it and if it doesn't seem to be healing within a few days we will be schedualing a doctors apointment. But for now it would be great if you could share your knowledge with me, possible causes, cures and mainly what it is.
Thanks in advance.
