There are several factors to consider when choosing a chastity device.
First, are you planning on wearing the device for a long period of time or a short period of time? Chastity belts such as the Men’s Locking Chastity Belt and Leather Locking Houdini Belt are highly effective choices for short term play. Chastity devices and cock cages like the CB3000 and The Brig are designed with slots that allow for bathing and urination and are thus suited for long term chastity play.
Comfort is also a factor, especially for extended chastity play. The Curve is a variation of the CB300 that was made for more endowed men, while the Bon 4 Plus is made of flexible silicone. However if you’re looking for a cock cage that also punishes erections then something like the Spike Cage will make you shrivel in fear.
We hope this has helped!
