First time must have been when i was late teens, cant remember exactly, but was taken to hospital with severe stomach pains, there a couple of drs felt around inside to find out what was wrong.
Many years of no drs doing it, just myself or a playmate.
Then with all the talk of needing to get prostate checked it was a woman dr who did initial check, she was plenty rough enough too !
Several times later in hosp it got poked , but male doc was ok, matter of fact, and not uncomfortable.
Had to see a specialist doc who was a smart looking woman, she felt around in there.........i liked her, she also had me stand to feel my balls , but not sure why.......
Follow up to this was with her assistant who touched something in there that caused my cock to spasm slightly, in different situation and a bit more of the same im sure id have come !
Last doc was my local one who felt in there after i had op to remove gall bladder and im now constipated or got the trots, be also inserted a camera to look. not painfull or exiting.
