instruction: hello doctor I am 24 years old I have always been very anxious about health especially my sexual health but when I was about or 10 a spot came up on my penis where the glans and shaft meet it was flesh colored painless and round there was no dimple in it I was never sexually abused or sexually active at this age I did not even masturbate the first time until I was 12 or 13 my mom took me to the doctor and they said like just come back if it gets bigger she had likened it to a wart but it was not very hard or dry anyway it stayed for a couple of years after that it shrinks down it no longer appears as if it is above the skin but appears as a small pin sized bump underneath a skin bridge I am curious if it cannot be an sad and I have never found anything similar online so what could it be I would not think a wart would stick around that long and it really does not look like that at all that was there over 12 years so I would not think it is anything fatal to be even more specific it is on the top side to the right as I said it looks like a skin bridge with a little bump underneath but it really has no sort of texture and the only problem it really causes is some skin rubbing when that extra skin rubs my underwear
output: hello this was likely a wart only warts can have very varied morphology and most plausible explanation is for wart only because considering it was a single lesion was not painful or itchy flesh colored and it persisted for a long time and resolved on its own so all these factors favor it morphology can be variable the negative factor was not sexually active although most common causes are sexual contacts but significant number of individuals may have it with non sexual contacts as well it can be transmitted vertically during childbirth and remain dormant for a long time activating later in life it can be transmitted with usual contacts and can be transmitted through clothing like underwear if came in direct or indirect contact with infected individual clothing sharing toilets etc can also transmit it so being not sexually active is not a strong factor against it rest all causes like skin tags which would persist without treatment or fall off suddenly up pearly penile papeles would be numerous papeles other infectious causes would be short lived and multiple lesions and symptomatic like painful tender or red malignancies are unlikely at this age and would progress so the probability is high for wart only I hope this helps
