Vibrators are nice, but it still doesn't feel that intense as have something "big" thrusting you from behind (or front for the females).
I use buttplugs and dildos/dongs, but I've been cutting back on the usage now since my lube supply is running low. For me, buttplugs and diapers don't mix because whenever I have something in my butt, it prevents me from peeing, and it will start killing my tummy later. I began anal play when I was 19, and now, I am able to use huge dildos that are 2.5 inches in diameter up my hole. Hopefully, I don't go bowel incontinence anytime soon. lol. Wearing diapers is fun, but if I had to wear 24/7, it would probably be a royal "pain in the butt".
EDITED
I'm not sure. The original gif image file was of a mommy spanking her son's bare bottom. I just cropped it to the restricted dimensions. I think it's from an Japanese anime made from a while back because of the graphic style.
