They may have been there for a long time, but I noticed them because I shaved the pubic hair
a little around my penis...something I usually do not do. I could see more of the skin now, in other words. I thought they were hair follicles or fordyce spots, although I was suspicious of them because they seemed a little more "on top of" the skin rather than under the skin, also no hairs ever grew out of them. Additionally, over time, they did seem to be getting a little bigger.
