Hi I'm a 16 year old boy and I have a lump where my penis is and it's been there for a week what should I do?
Hi Sean,
Where is the lump? Is it ON your penis?
I'm guess that you have sebaceous cysts on your penis. Basically it is a swollen oil gland, like a zit. The skin is very thin over your penis so they tend to be more pronounced, visible.
It should go away in a few days. Warm compresses can help it drain.
It is unlikely to be an STD.
Hope it helps.
