Question

There are bumps on the shaft of my penis that look like goose bumps. What are they?

Answer

Mostly likely what you are seeing are hair follicles. Yes, you can have hair on your penis. It won't be a lot, nor will the hairs necessarily become long or dark, but hair on the penis is common among men.

Cross-section of a hair follicleWhen hair first develops, it is very fine, but the opening it must extend through in the skin is often very small at first. As the hair moves up, it pushes on the edges of the hole, causing a small bump. In time, the hole enlarges and the skin lays flat again.
