I am 15 years old and I have noticed small bumps on the head of my penis about 2-3 years ago. They don't pop or anything, but they are sensitive. Is this a skin condition or is this supposed to happen?
Your description is too vague for me to guess about what you are seeing. The head of your penis, called the glans, is highly sensitive to touch. During adolescence the surface of the glans becomes rough. It is especially noticeable when you have an erection as these rough areas spread out. The purpose is to give you strong feedback during sex. The least touch moves the rough areas and sends signals of pleasure back to your brain.
Some men develop a series of bumps along the bottom edge of the glans. That edge is called the corona and the bumps are called pearly penile papules. "Pearly" because they are white to yellowish in color, "penile" because they are on the penis, and "papules" because they are bumps. Click here for a picture of what it looks like (courtesy of Wikepedia) and click here for another photo. They are harmless. About 8 to 48% of all men have them to varying degrees. I don't know if this is what you have or not, but you can write back with more details if you want more information.
Thanks a lot. I really appreciate the help and information. You don't know how much better I feel knowing that it is a normal thing! Thanks again.
