Swollen bump/lump under penis skin

Hi all,

Hoping you may he able to help me figure out what my issue is. Recently I’ve noticed I have this kind of swollen bump under my penis skin on the top part of the penis near the dorsal vein, its kind of round and a bit hard to touch and it isn’t noticible but i can feel it when erect. I should add it isn’t sore at all.

Maybe I’m overreacting but my mind just thinks its some sort of unknown bump it must be a bad thing! could it possibly be too much activity and its irritated it?

Sorry for lack of pics to back this up as I said you cant actually see it can only feel it.

Thanks!

Likely to be a penile cyst, do not aggravate it in any way, it will only make it larger …
