Dave,
I have had a diaper fetish for decades and I have always been hesitant to share the fact with my lady-friends. I have only shared it with one, and I was quite surprised that she was not in the least concerned about it. We never got the chance to experiment with it.
I believe in my case it is linked to a traumatic event when I was about 4 years old. It was at that point that I regressed and started nightly bed-wetting until I was about 14.
My mom had kept my old diapers in the house after I had outgrown the malady, and I discovered them one day when I was skipping school.
I started wearing them again when no one was home while I was skipping school and began to make many excuses for not going to school. Wearing them led to masturbation in them and I was hooked for life.
Even when I was married, I would sneak hand towels into my underwear to simulate diapers. I don't know nor do I care now if my wife knew.
I have now advanced in years, I have no close relationships, and more than half of the porn on my computer is women wearing diapers. I only like dry, clean diapers; I'm not into urinating or defecating.
The one very positive thing I can say about loving diapers is that it hurts no one except perhaps myself, and I don't even believe it does that.
So cheer up. If you find an open-minded woman to love, I can't imagine she will have an issue with it. Everyone has some kind of sexual issues, anyway. Some are quite bizarre in my mind. The big issue here is that most people in our society don't talk about their sexual fantasies except with their partners.
