I think you're missing the point Russell- a chastity belt is not so much a foolproof way of stopping your loved one having pleasure- that would be illegal & nothing short of abuse.

Most people I know who are interested, see them as a pleasant reminder of their submission- or just a hot item of fetish wear.

One thing I have heard, is that some of the leather ones can be very uncomfortable & bulky. I believe you can get them made to measure if you have the money.
