"I still don't see how people hide this from their spouse and live. My life without diapers wouldn't be nearly as much fun. " - Darkfinn
Well, you have to remember that we've been together a long time, our youngest child is older than you. I pretty much know after all these years what will and won't fly. Even if I thought it would, this is one of those things that could easily turn into obsession for me and interfere with too many other parts of real life. So its just as well to keep it on the down low.
Should I have said something before we married? Maybe. Except it was kind of in remission during that time, and I wouldn't have known what to call it or how to describe it. Remember this was long before internet, so I was hardly aware that I was not unique, or that this fell into the same general category as whips and leather. I mean, intellectually I realized that there were probably more like me in a world of several billion people, but still.
For now, I get enough privacy to satisfy my need, and by the time we both retire and see way too much of each other, one or both of us may well be dead or incontinent anyway.
