Neither tighty whiteys nor boxers have a place in the life of some. Briefs are "out" ... boxers are extra baggage around the legs and in shorts and pants.
Someone please explain to me a good, solid reason for underwear for men (myself) other than worn as a bedroom charmer. Do so and I'll change my ways - after 20 years with no need for either.
Locker rooms care less if you have of have not. Next is doctors and medical professionals and they are all accustomed to anatomy. It is neither a plus or a minus. So no need for tighty whiteys or other unless you like being smothered. If so wear something comparable on our head, your hand for a week and you just might see how things encompassed in tighty whiteys feel.
