Not sure what to make of it, but I noticed about 6 weeks ago a single tiny whitehead looking bump toward the bottom-mid part of my penis shaft. Fast-forward to today, and it appears to have grown in size slightly, but still relatively small (maybe the size of a pencil head). There is no pain, soreness, or irritation associated with it. Just would like to know if its something I need to be concerned about.

It kind of reminds me of those little fatty pockets people get on their faces near the orbit regions (looks like a zit, but isnt).

Any advice is greatly appreciated.
