I’ve had this bump on my penis shaft for awhile now and I can’t really figure out when it first appeared but the size and appearance of it has changed in the last 6-12 hours. The thing started off as a small smooth bump but has turned into a yellow pimple like cyst.
I’m not sexually active at the moment and the last time I had sex was January 1st 2021.
The pimple thingy doesn’t hurt (and I haven’t felt discomfort in the past months). could someone give me advice on what it could be and if I should see a doctor?
