Just to say hi and thanks for having me. Was looking for a review on the Bon4 and goog*e brought me here. in and out of chastity for some years now but never found one that i wear for any period of time without it trying to castrate me in some bizzare way!! Tried all the CB range, and Exo. PA5000 was ok and by far the easiest to use but the PA part of the device is plastic, this means that the very tender skin sticks to it causing it to bleed...not good and caused a certain Mistress to get well cross! Anyhoo, I'm bigdav
