Hard, pea sized lump under penis skin since childhood

Hey everyone,

I’m 24 years old, and I’ve had this small, hard lump under the skin of my penis for as long as I can remember. I first noticed it when I was around 7 or 8 years old. It doesn’t hurt at all, and it moves around when I touch it. No changes in size or shape over the years, and it’s never caused any issues no pain, no discomfort, it’s smaller than a pea and it’s round, hard as rock.

I never really thought much of it, but recently I started wondering what it might actually be.

Just looking for some insight or reassurance before I bring it up with a doctor. Thanks in advance!
