Actually, my nuts were slow to drop in the first place. It was a concern for my mother. Several times, over the years, one would pop up on it's own. The first time, I was rather concerned, wondering what happened to it, but it didn't take much poking around to find it, pop it out, and back again a few times, to make sure there was not something real strange going on. So, I never had a problem with this element, and now, on hormones almost 3 years, with the shrinkage, there is no discomfort at all.
I answered it was something I had to learn, because the other elements (forming a tube with the empty scrotal sac to prevent the nuts from dropping out) did not occur to me.
I will say, I can tuck for days at a time with no discomfort. Sit, stand, dance, with no slippage or discomfort. It feels perfectly natural, and more comfortable than having that junk flopping around.
