From about 5yrs old I had a "thing" for pilchers [plastic baby pants] and also panties. I would borrow these whenever we visited relos with young children and later, around 10, would buy my own pilchers, wearing them either under my briefs or by themselves. I'm pretty sure at this time there was no interest in nappys. Well, by age 16 I grew too big to wear pilchers, even in the biggest baby size on the market. It was'nt untill I was about 44 that I discovered that there was such people as AB/Dls and you could get adult size plastic panties. It didn't take me long before I had my first pairs of plastic panties in almost 30yrs. It was then I decided to try nappys and I am so glad I did. I now have quite a collection of plastic panties, disspossables, pullups, cloth, and training panties. I do this both for the feeling of comfort and also there is a sexual side to it. :
