question: So, a few days ago I was masturbating and after I was done I looked down and saw a bump on the left side of my penis,its on the middle of the shaft, not near the head or near the base. It looks like its a bump under the skin because when i would move the skin around, it would move with it. It doesnt hurt to the touch but when i try to apply a little bit of pressure to it, it ll obviously cause a little pinch. It s not big at all, about 2/3 the size of a pea but im still concerned. It s hard but not like a rock, it s kind of hard to describe it. I researched a lot and I thought it was a lymphocele until recently and I think it might be a cyst, and I ve been going back and forth. It doesn t go away and come back as far as I know because it hasn t gone away yet. I haven t masturbated since I got it because I read that you shouldn t if you have a lymphocele because it ll irritate it.
