I have been watching some videos and one thing I noticed is that we ABDLs tend to fondle our diapers in very common ways. I know I do it all the time, and I see many do so in the videos.
I also noticed the blissful expression on one girl as she wet herself and I immediately recognized it as what I probably look like at times when I am wetting.
I know for me that the feeling of wetting my diaper is second only to sex, and that fondling my diaper is very enjoyable indeed. While it is not surprising to see this in others, it is something that gives me a feeling of not being alone which is quite nice.
It just seems to be one more aspect of the experience and for me it certainly adds to my enjoyment!
