Some women appear to have a habit of wearing no bra and panties on the bed, but it is not common among men. I am an averaged person and I have never slept without underpants before last night. I was worried I would catch a cold but nothing bothered me at all.
Sleeping with no underwear may have a few advantages.
- Can save money to buy underpants.
- Can save time to go to clothes shops.
- Can save water to do the laundry.
I am not going to encourage you to give it a try because possible contribution, if any, is a bit. However, no-pnats-sleep may be invaluable in a certain situation. For example, it would work well in August in Japan because it is boiling hot and disgustingly humid.
At last I have to say that wearing no underpants was very handy when I went to the rest room. Concerns about poor sanitation were raised, though.
