I really didn't expect to put another response here but since it seems I have told that I missed the point I will.
The only reason I can think of for the use of this belt, which I also feel is a risky business for the lady, is that the lady is thrilled at some level by it. I find I can thrill her more in other ways when I am not near and I damn sure I can find ways to thrill us both more when we are together.
