Chastity and orgasm denial discussion

So my question is, how much has chastity conditioned your body’s responses? I realized today that for me, the answer is significant. I get to cum fairly rarely, about four or five times a year. After the last couple of occasions when my wife and I had sex and she experienced an orgasm while I was still locked up, my penis suddenly went limp in the cage, as if I’d just come. Today my wife noticed not only that, but also that my skin had flushed like hers following her orgasm. She was actually quite amazed by it. It seems that my brain has told my body we’ve both experienced an orgasm.
