Hi, 

Im wondering what this lump under my foreskin is... It's round and small, like 2mm diameter and hard. It doesn't hurt when I touch it and it doesn't seem to be actually attached to my penis because I can grab it from underneath. It's like it's part of my skin but I know it's underneath. I've had it for like a year near the end of puberty but never batted an eye on it because I thought it's normal but it stayed, and I'm asking for advice because I noticed that it's bigger than it was. I'm a lil freaked out because of all the  results I got when I searched for it. Any help would be great. Thanks! Also I have a photo if anyone asks for it for what it looks like.
