I’m a guy and I have seen a few “leaks” and when I did I was mortified. I did not know what to do or say. In retrospect I wish I could have been more mature and able to say something tactful to the ladies. Once I was grappling with a lady who had just had a baby and she advised me about another problem called “bladder control”. Now that I have kids of my own, I know what she was talking about. My wife does not like to run nor do jumping jacks right now LOL. In conclusion I will say this; if a female comes to me in class and says “sensei I can’t do that exercise today” or “I can’t spar today” I will just say “OK no problem, go practice kata” So I believe a good policy would be “no questions asked”
