I know this will probably be highly frowned upon, but starting with Akido in Jr. High, then a short stint with Cobra Kai, while in New York for a summer after seeing Karate Kid (Very brutal mix of Shotokan, or so they say)then 20 years of Shotokan. Until 7 years ago I traveled all over the world for work, so I used an indwelling catheter and bag often. I found by using a catheter plug with a pad inside my cup allowed me the freedom to not think about it for at least a few hours a day when in the Dojo. I never had a problem with the catheter, but I took extreme care to guard against infection. Not knowing what country I might be in & when, and what kind of medical care might be available I had to be extremely cautious. During my 30’s I competed when I could until someone from one of the “BIG BANKS” called my boss (a good friend of mine)and told him I frightened some of the staff walking into the executive offices with black eyes & stitches a time or two! In hindsight I highly recommend the head gear along with whatever other protection you need, in my warped mind it’s all the same! The Attends Belted briefs were very easy to hide as well. I laud you, what a great way to keep your mind & body focused!
