Chastity cock cage to wear during anal training with a dom male

A dom male wants to shave my circumcised penis and balls and have me wear a stainless steel chastity cock cage during anal training. What are the pros and cons of wearing a chastity cock cage? Can anyone suggest a stainless steel chastity cock cage to purchases?

I have three stainless cages, One is a multi piece that you basically assemble as it's put on. I have two that is a two piece, a ring and cage.

The two piece are my favorite, fast and easy to put on without torturing the jewels. The other plus is no pinching of any skin.

The multi piece cage is harder to put on and pinches tremendously. I don't recommend these types. The best advice is measure yourself and get one that FITS you.

Amazon has a decent amount of cages of all the different types and instructions on how to measure. There are a few cages that comes with different size rings which is nice at a decent price.
