I’ve had this bump on my penis for months and don’t know what it is

ive had a bump on the bottom of my shaft for since probably may of last year. i thought it was a pimple over the summer and tried to pop it, and got a little bit of stuff out but it never went away. recently it has gotten bigger. it feels like a zit but i can feel the inside of it and it is hard but still kind of squishy. anyone know what it could be?


heres a photo for reference if it helps anyone get a better idea

ive had one too. been to drs and they think its a papule i’ve been referred to dermatology for it removed.
