Chastity device discussions and reviews discussion

Sorry if this has already been talked about. I’ve owned

1. CB6000 - It was my first choice, but I found the cage too long, which caused a lot of rubbing and friction burns on my penis during sleep.
2. CB6000s - This one was quite good, though it still felt slightly loose.
3. HTV2s - This is what I’m wearing now; I love how comfortable and well-sized it is. The only downside is that it can get a bit humid and sweaty inside, which isn’t ideal for my skin (it can slowly lead to irritation). So I’m looking for advice on any metal options similar to the HTV2s. I want to switch to metal because it won’t be completely sealed off, hopefully stopping the sweatiness. *NOTE: Usually, I wear the device from 7pm until 7am and make sure to use lubricant on the ring, but not inside the tube since I use the stocking technique for insertion. Thanks ahead of time.
