I've never had the pleasure of a chastity device, though for a while I had a thing going with a female aquaintence, to see how long I could keep myself 'chaste'. Suffice to say my willpower wasn't quite strong enough and I failed after a short time (though I enjoyed the punishments that followed) I'd definately like to try one of these at some point, though at the moment I don't have anyone to try it with.
