I wear one and my wife holds the key. I wear a
CB 3000. Have had it for a little over a year now. We bought it together online while we were shopping for new adult toys. We wanted a toy that she could use on me. If your wife is into it, it is one of the best purchases you can make. At first we just used it for short periods of time, then I told her I wanted to go for longer periods. Now I pretty much wear it all the time, except for when she removes it. She almost immediatly noticed that I started becoming much more attentive to her when I was wearing it. She loves that we now spend more time kissing and hugging, holding hands etc. So if you are trying to get your wife into this, just tell her that it might be fun to try and that you are interested in it.
