So..I'm 18 years old ( and virgin ) . I have a lump on my penile head ( along with two others that aren't big in size and not that visible ) . The lump is on the left side of the penile head and it's about 0.7-0.8 mm in size and kinda raised above the surface it is dark colored ( purple ). This lump along with the others mentioned are there for more than 2 years and haven't changed in size or something.
