Hi, I’m 21 and have the exact same thing. I assume it is nothing to worry about as my penis has been seen by doctors before and they have never pointed it out. Would be interesting to see what it is though. Hopefully someone can enlighten us.
I would suggest this is simply natural development - it may be linked to the regular presence of pressure withing the penis.
So this would be linked to the overall amount of time your penis is erect - so here it could be linked to sex, masturbation, or using any method of penile enlargement / development
Other than see a Urologist there is not much you can do about these once they develop, other than reduce the amount of time your penis is erect, and / or abstain from any method of penile development
Hey mate. I have the same thing and im 19. i have had it for a few years now and it has gotten slightly larger over time. The only thing i worry is that it will impair my penile function. But it hasn’t so far so i guess its fine.
