Chastity and orgasm denial discussion

The first time it happened was completely out of the blue. My wife doesn't usually get involved much in my care; she did a little at the start, but one afternoon she mentioned getting a call from the caretaking agency because they were busy and couldn't come that day. She told me she'd handle things herself. She turned me onto my changing mat, pulled down my shorts, and took off my diaper. I was wearing both a cage and a catheter (leaking urine through what's called bypassing). She said she'd do a few tasks to let some air reach my skin. Then she stepped out, and shortly after, the doorbell rang with voices outside. Closer to the entrance, I heard her explaining that she was in the middle of changing me. She talked about the cage being there to prevent unwanted erections. Right then, I realized who they were bringing over. In walked my wife, chatting away as she pointed out my cage and catheter while cleaning up around them—the whole show. The two women seemed really interested. I felt so embarrassed! Even after they left the room, they kept asking questions, particularly about the cage. My wife mentioned that I get frequent erections whenever caretakers change me, which is why their manager had called her. I never expected to have to endure that. Though she clearly enjoys it.
