We love this TV show, even the stuff that doesn't cover our interests. Overall, I think it is non-exploitative and not sensationalized. It's hosted by Karley Sciortino who is great.
The episode on "Lifestyle Slaves" has had quite an impact on my wife. She said she noticed how I "lit up" watching it, and is realizing how things could be more worked to her advantage. There is a brief discussion of chastity on the episode, but also a lot of discussion on how the subs can be personal assistants.
We've been together 20+ years, experimenting most of that time, and still discovering new and surprising ways to improve or things to try.
