I've never worn butt shaping panties either.
I always wondered if men were disappointed once the "reveal" showed the voluptuous boobs in fact, were the effect of a gel filled Wonderbra. Or, if the rounded, tea-cup-holding ability of a woman's ass, proved to be skinny or saggy.
Regis was showing Kelly these padded briefs for men this morning.
I'm not one to check out men's "packages" [ahem] but on the occasion I may watch as they are walking by, I'll have to remember these. I think I would feel slighted if what I was seeing was an illusion.
