I love crotchless panties and always let my OH know Im wearing thrm before going out, I then feel sexy all night a huge turn-on for both of us.
Plus you can still feel safe wearing them in a short skirt in preference to going commando as should anyone get a view it looks like normal panties.
Plus they look so erotic being pulled aside for sex, I think most men like their partners semi naked, this does exactly that.
But I have found some can accidently get in the way...ouchy!
I hate crotchless tights though; Im a stocking kinda gal.
