I've liked wetting for as long as i can remember--I have a few very detailed memories from my childhood, and almost all of them are incidents where I wet, and it always felt really good, and I could not figure out why. (I would later discover that the feeling was arousal/sexual pleasure, I just didn't know what I was yet.)
I know what I like, but I still don't know why I like it. But I do, and there is clearly no changing that--lord knows I've tried.
