Hair ON the penis.
I noticed today that I have three hairs on my penis, about half-way up. They are small and hard to see right now, but they look like hair does before it grows all the way in, like when there is no hair and it grows in at puberty. I am eighteen, and puberty is taking awhile for me (no facial hair, no arm hair, a bit of a happy trail). I really don't want this to be something that grows all the way out, like a few pubes missed their target, and I REALLY don't want more of them.
Hair on the penis is very common, most guys have it by mid adulthood and either leave it or shave it.
