I, too, absolutely love the smell of my wet cloth diapers. I love them when freshly wet and also after they've spent a day or two in the diaper pail. Like many of the others on this thread, I will take them out, smell them, and if I'm alone, I too like to rub them on me so that I wreak of pee.
If I'm alone I like to wear my diapers with no plastic pants and sit on a towel and let them dry on the outside as I continue to wet the inside, and enjoy the pee fumes that drift up as they do. It's really fun to do this outside on a hot summer day (but I don't often get the chance).
I take them out of the diaper pail and smell them and sometimes pin them back on and wet them again and again (and get myself off in them each time). I just absolutely love this.
This probably all started when I was a kid. One of my earliest diaper experiences was when I sneaked into the bathroom of one of my younger girl cousins and smelled her diaper pail. It was full of yellowy wet pee-soaked stinky diapers! I got such a rush that I almost fainted and kept making excuses so I could go back in there and smell it again and again.
I also used to regularly look through apartment complex dumpsters or trash cans and take wet diapers home to enjoy (but I quit doing this years ago after I caught an upper respiratory infection this way). Once I was lucky enough to live in a small apartment complex where one of the other families had a crippled teenage daughter who was always in diapers. Every time I took my trash out, there would be a brand new bag of them and I'd help myself. This was back in the 1980s and I'll bet that during those few years I jerked off enough to cover a hockey rink.
My latest fun thing is wetting in a pair of white "adult" training pants then hanging them up in the attic to dry, then doing it again and again. I love it.
