Thats great! We girls love to wear our sexy undies just to feel more sexy and more confident, and it works! We don't wear them just for the men y'know!
Unfortunately, I don't find there is as much of a range in mens undies as there are womens which is a big shame. I will have to have a look around for some for my OH for the december holiday.. Maybe some nice satin ones.
I kinda wish there was a better range, so men don't have to go for the same old Calvins (which are practical, but not really sexy) or resort to novelty undies which most are tacky or have Homer Simpson on, or even worse (in my opinion) pouches!
A chastity belt is something quite different. But I do understand where you are coming from. There is an ever growing range of chastity belts, for men and women. You can even get some that look like chastity belts but are escapable..
