Input: Text: i went to the dermatologist today for a full body cancer screening (i have a lot of freckles). i've done these before and normally just stand in my underwear while the doctor looks at all my spots. this was a new doctor and he asked me to lower my underwear and stand naked while he examined me. he had me turn around and i realized my penis was getting semi erect. i hand no idea why as i was not sexually excited at all.  i got very embarrassed and apologized. he said he it was no big deal and it happens all the time, but i was still humiliated.

TIFU by getting semi-erect at the doctor
