I also received comments on how long and hard I have peed
She said wow you must have had to really go bad.. I did too I had been holding it for a long time and was really desperate.
I took that as a compliment on my pee holding ability, and her appreciation of my stream
I've gotten the occasional compliment on the duration of my piss from a girlfriend. I took it to mean I was doing well for a guy as she can blast full force for a minute and think nothing of it.
My experience in Japan is the toilet fixtures just continued the sexism. Minimalist squat toilets for the women and excessively bulky urinals for the men.
