Mine never comes out except for cleaning.
I do not waltz around nude with it, even at a gym, but neither to I take any overt action to conceal it. If I am in the shower, there it is, but otherwise I would have a towel on.
I have never taken it out to see a doctor, but would if they were giving me an MRI or needed to put a camera up my dick...
No Doctor has never commented on it.
I do not display in a public restroom, but there have been occasions when someone has tried to get a look at my dick, and they react when they see it... but then they never ask about it because, it would mean admitting they were checking out other guy's dicks.
It hurt to do it ( it did it myself ) but not any worse than a stubbed toe, and only for a short while. When I extended the PA into an apadravya by putting the hole all the way thru the top center of my cock head, that hurt a little worse, and it ached for a week afterward.. but again, the anticipation of it was far worse than the actual doing of it.
My experience may well seem less painful because I was actively doing the procedure myself... so I had a point of focus and a sense of control that always seems to make pain less intense.
I did not do it, nor do I wear it, as has been suggested, to get attention.
Partly, piercing myself was a trial, a way of proving to myself that I could do what I put my mind to.
Partly, it was sexual, I find piercings erotic and sexually exciting.
And partly, it was sensual, I love the sensation of it, the very idea of it.
And I particularly like that it is unobtrusive and secret. ( the opposite of seeking attention )
It is something about me that only is shared with an intimate.
If I don't include the doctors, the number of people in my life who are even aware I have one is probably less that 4...
