Most of you are interested in the curved/bent metal cage. We love it, because it's quite an open design which allows me to tease him mercilessly using my tongue along the whole length. The curve is great because:

• It keeps the cage secure, as the erection is not able to push it away
• It protects the foreskin and/or glans from rubbing against the trousers
• It makes the cage less visible through trousers

The only gripe we have with it is the limited space between the cage and the ring which sometimes can make the wearing or sitting uncomfortable.

We got the cage from aliexpress; it was sold under the brand name Ternence; it is compatible with other generic cages with the hinge ring design.

The older, straight metal cage we use (also compatible with the cage above) was sold under the brand name Happygo. It is also a great design generically sold by several brands.
