Hey I am 13 and I have noticed that there are small bumps on my sac and some on my penis but I don't know what they are and also a sort of line on my penis can anyone tell me what it is
Hi guest,
The bumps could be either where hair is going to grow or oil glands. Some bumps are normal.
The line you see on your penis IS normal. All guys have it. It's part of how our bodies develop, called a "penile raphe."
Hope it helps.
