When I feel the need I wear boxer shorts.You can go anywhere in public in boxer shorts, T-shirt and flip flops.Jock straps are not comfortable to me.
I wear gym shorts instead of boxers.
Just as comfortable, even more acceptable, and not designed to be underwear.
I only wear a shirt where it is required in warm weather. There are many places, especially outdoors where a male can go without one.
i had to think back and laugh about the jock strap being required for pe class in junior and senior high ,i grew up in south florida the list for pe class - white t shirt , blue gym shorts, jock strap , white socks and sneakers back than i don't remember them called tennis shoes . south florida winter is january & february and that's not always true so beat the heat it didn't take long to forgo the jock strap and only wear t shirt , shorts and sneakers and kickball and football you wanted to be on the skins team.
