I'm a 17 year old male who is uncircumcised and not sexually active. For as long as I can remember I've had a hard lump at the very end of my foreskin. The lump is somewhere between the size of a grain of rice and a pea. It does not hurt unless squeezed, in which case it feels like the skin is being pinched. The lump is not exposed, but within the foreskin itself. There is no discharge of any kind, it just looks rather odd. It's oval in shape, but is split halfway down the middle, making it an unusual shape.
What is this? Is it harmful?
Any information about this would be helpful. I've looked around the internet, and some people have asked the same question but with no response. Hopefully this one will be different.
Thanks in advance.
