As an American, I kinda have to agree with you.  I shower if I get some stinch on me which does usually come to about 3 days per week, but the daily showers are way too excessive imo.  Of course I'm not obese, I'm not trying to be rude but it is what it is larger folks sweat more.

I still think underwear daily changing is good.  But every other piece of clothing can go so much longer than that provided you haven't sweat through it on a 90 degree humid day.

I feel like i keep my d**k and a*s clean enough for my boxers to not smell like death lol. When I hit the gym tho... I have no choice but to change
