Dude,

Don't know how old you are...but I am 39 and I have had them since I was in college. I have shown them to a couple of doctors, and they were not concerned. It has been 10-15 years since a dr. has looked at them, so I don't remeber they are called. They're not ingrown hairs and you might have them from now on. I have never had a chick "nut-up" because of them. Sometimes you can pop them when you get out of the shower, but popping them does not make them go away. Now if you get a small (about the size of a pin head) zit looking thing on your shaft or foreskin...well...that is a different story.
