I have a very small, but hard white lump, completely painless, on the shaft of my penis. I've searched and searched online and can't find anything that matches this description at all. It's just sort of solid and is fixed in place under the skin. Does that sound familiar to anyone?
I know it can't be genital warts, because it doesn't have that cauliflower look, and its just the one. It's a millimeter across. Been there about three weeks. Doesn't match the appearance of herpes, plus there's just the one (besides, I was tested for herpes a few months ago, and it's pretty unlikely I contracted it since then).
Doesn't hurt at all and isn't particularly visible when flaccid. Google image searching syphilis, it doesn't match the appearance of anything like that. I have been sexually active for several years (aged 22), but always use protection.
So any clues? I'm planning on seeing a doctor ASAP, it's just a matter of money and time. But in the meantime it'd make life less stressful for me to have a good idea of what it could be.
