Dont mess with them, especially that whole popping thing.
You can give yourself nasty, painful, infected, pussing, leaking (are you getting the point!!)
Basically, leave them alone, and I agree with everyone that is is normal!
Because of the proximity to your testes, an infection could cause you to become sterile, and many other things that you wouldnt like.
If you really are bothered by the bumps, talk to your doc, I know that there is something similar to DERMABRASION ( a horrible thought) that can be done to remove the spots!
