I stopped sitting on toilets about 14 years ago after a camping trip when I realized how much I preferred squatting. I will never go back unless forced to due to injury.
I believe it's part of the reason my upper leg muscles have remained strong even when work has put a halt on exercise for longer periods of time.
I would be open about this if asked but never bring it up unsolicited in conversation as in the past I have found it regarded as outright bizarre.
