About a month ago, I noticed a very small hard bump on the left side of my penis. It's black and about the size of the actual lead tip on a mechanical pencil. It doesn't hurt or itch, but it bothers me. Sorry to be graphic, but I first noticed once masturbating and now it bothers me all the time. It's also there, but near as prominent when I'm flaccid. I haven't had any sexual contact since January and it just came out of nowhere. It almost feels like I could pop it out, but that kinda freaks me out. I'm really hesitant to see a doctor with covid and because it's really embarrassing. Any thoughts or experiences would be greatly appreciated.
