Hello. My wife and I started with dom sub dynamic about a year ago. It lasted for maybe 3 months and kind tapered out. I recently suggested we start it again. I like that cock cages but I do have concerns with hard to my wife's important tool. I would like a cage that allows a full erection (or close to it). I saw that one that is made of chainmail. Something like that could work. It could even have a cotton liner...
