with these two I have found no recounts of how they feel to be worn, short term or long term.
Leather Chastity Belt
This would be recommended for short term use and is very affordable to buy.
Leather can be easily cut for escape and is not found to be hygienic for long term use, the dampness causing chafing of the skin and sores along with leather holding bodily scents or smells and difficult to clean.
Plastic Chastity Belt
Again affordable to buy (at around 100$) easy to cut for escape, better for long term with two plastic bands in the back, good for hygiene and easy to clean.
