I'm a DL. I was a bed wetter growing up (As I assume many ppl here were). The problem persisted into my teenage years, and though it has vastly improved, I still have quite a few accidents from time to time.
I live with my high school sweetheart (now Fiancee), who has known about this problem for a few years now. I'm not sure when the fascination with diapers started but I have always worn them for certain situations (anytime I drink alcohol, get sick ect..). That didn't change when we started living together, she is quite supportive and doesn't seem to mind most of the time.
I suppose the only problem is that I have not told her that now I REALLY love having to wear diapers, and it is a sexual thing for me. Also, at times i have made her believe my bed wetting is more out of control than it actually is... to the point that right now I wear diapers every night even though it's probably not necessary.
