Kegel exercises for men, Mayo Clinic shows you the ones that work for bladder control and may be helpful in other ways (felt impotent for quite a while, but now my wife and I have noticeably better sex thanks to the exercises.

Still, when my bladder is ready to burst or I feel the need to empty my bowels, I have little time before I start to leak--happens several times/week. With a bowel movement, I explode; really have to make sure I go before leaving the house, and when it's time for me to go, I go all out to make it to a restroom. I make sure there's a restroom in the store or restaurant I'm in; I don't get much advanced warning for either, so I always have an advanced strategy for both. The Veterans Administration gave me a few dozen diapers/"Depends" which I have yet to wear--I'm thin (used to be skinny when I surfed or played tennis or did martial arts), but that was before I had PD to deal with along with aging. I eat quite a healthy diet, drink three liters of water/day, but I'm housebound these days--avoid going out and risking having an accident. I just got a new e-bike today and my balance and rode it the four miles from the bike store back home was in the lower end of OK, but at least I felt mobile and more normal--tremors under control but body more rigid than going back 6-7 yrs. I guess I'll have to wear larger pants before I try wearing diapers. I'm only 73 and had been healthy and physically active before getting my PD diagnosis which was around the time I had to deal with semi-incontenance. My primary care physician said there were med's I could take, but I'm way overmedicated than necessary; been titrating off as many of them as possible--no longer taking PD med's: just being tough or perhaps hard-headed (an ex-Vietnam vet Marine) with a lot of willpower. Good luck. There always seems to be a way of dealing with anything and everything. We all got to where we are, and just about every one of us had hiccups along the way.
