The chastity device in this photo is called a “Latowski”. It’s incredibly effective. I wore one for a few hours, sadly it wasn’t the right size and it dug into my hips like a vice. These need to be custom made. The web site for Latowski’s seems to be gone. So, if you can get your hands on one, do it.
The hood, which I have, I can’t recommend enough. Its the Puffy Hood from Mr S. It’s VERY comfortable for very long periods of time and great for sensory deprivation play. Top Notch.
Here’s the website:
