I had them and HATED them. Four years ago I decided to be circumcised - I thought that might make them fade as a couple doctors told me it might. Four prominent papules were removed with my frenulum but after two years the ones on my corona were still there - perhaps they faded a tad. I decided to try cryotherpy - freezing them off. That was not successful and quite painful! Then finally, a year ago, I had laser treatment to remove them. Complete success!
However "normal" they are, I was not comfortable with them. For those who don't mind them that's great. But if you don't like them, they can be removed.
