Currently, Amazon US has a chastity device at Number 12 in "Best Sellers in Bondage Gear & Accessories", with a paddle at number 11, and everything above that being basic bondage gear. However, no CBs feature in the Sexual Wellness top 100.attentive_husband wrote: ↑Thu Dec 13, 2018 11:17 am One thing that makes me think it's pretty wide-spread is the number of units for sale on Amazon. It's a ton of Chinese knock-offs and they don't do that unless there's volume.
In 2017, male chastity devices werekink.com's top sellers in two US states.
I conclude that male chastity is at least mainstream with people who buy bondage gear...
