Does anyone know what this lump is?

Iv had a lump on my foreskin for a couple months now.I tried to pop it as i thought it could have been some kind of a zit but the lump feels hard.I have tried to cut my foreskin so maybe something could come out but it just made the lump bigger.

Lew, it would help if you can upload an image or 2 to identify what you have, you may need to do this from a Laptop or a PC.
Do you know what caused the lump to occur?
