Navigating the commitment of lifelong chastity within a couple

I’m looking for advice from other members who have taken the permanent chastity path. My wife and I had a small disagreement last night because she is questioning keeping me locked up forever. She has no interest at all in using my penis, but feels guilty since she thinks it’s harsh on me and that I should get to have intercourse and an orgasm every now and then (even though she hates the experience). What would you do? I got through those initial weeks when I was unsure myself, but now she is struggling. Any ideas? Just as I started accepting that chastity would be permanent for me, her doubts are surfacing.
