hey, I had this lump on my penile shaft for a while now , and it doesn't cause my any pain or discomfort. There were 2 occasions where I "popped" the thing because it looked like a pimple and it did ooze yellow liquid, but wasn't smelly so I don't know if it was pus, and it's size got smaller (this was months ago) . But after that it didn't go away and I still have it and it doesn't have a yellowish colour, could this be a cyst? Thank you
