Chastity and orgasm denial discussion

Hi everyone! I’m brand new to this site and to chastity as well. My wife is kind of onboard, but has no idea the power she could have… anyway, I put on a cb6k for the first time a week ago. Day two she let me use a strapon on her while encased, and the next night she returned the favor. Day four I got out and satisfied her for about an hour without cumming, then back to lockup. The next day she told me she felt bad that I didn’t cum, so she took the device off. She masterbated me, and I came. Now I can’t shake the feeling that I failed; I don’t have the urges to please her like I did on day three. I don’t want to be allowed to cum like that at least not so soon, but my wife doesn’t understand. What can I do? Instead of feeling good, my orgasm has left me feeling empty and like a failure…
