Where do you guys go commando
Much more likely in warmer weather when wearing shorts. Running shorts are the best. Although I'm gradually turning into a 'whenever I can' type, I think.
Maybe it can be noticed on me if there's a bit more bounce beneath the fabric; for females the presence of underwear is usually more noticeable through the lines that invariably show.
I go commando all the time except for my exams at the dermatologist. When I go there they tell me to strip to my underwear, which I can't do if I'm not wearing any. So to save the others in the room for my exam from embarrassment, I wear undies for those exams, but that's it. I sometimes wonder if others can tell. Some of my dress slacks are thin and I wonder if my rim is identifiable.
I go without underwear whenever possible. I recently bought a pair of short length board shorts by Zero Foxtrot. They have a 5" inseam and no liner. They are the best. I do not care anymore if I have a visible outline of my penis to some degree. I like being able to be free and when I walk he gets to bounce around like normal.
