Women can wear any type of underwear and all colors available while men have to stick to certain styles?

It is okay for women to wear many type of underwear such as panties, thong, boyshort and many more and pick any color they like. Men on the other hand have to stick only to boxer or briefs and that's not all they can only wear certain colors such as white,black,grey and blue. women will make fun of a man who wears underwear with graphics such as sponge bob.
