Hello! I have this weird lump on the base of my penis. It's right where the scrotum meets the shaft and right where the hair stops growing. I shave down there and I was wondering if it's possibly and ingrown hair, but I can't seem to find any sign of any hair inside. When I squeeze it in attempt to pop it, sometimes a very very very very small hole opens up releasing a very small amount of puss. Just today I tried squeezing it and instead the areas I was pusing with my fingers, got a weird red color as if there was blood under the skin. Could this be a cyst, or a blood vessel? Thanks for all the help!
