Yeah, I wondered about that for him. What I meant before is to get a huge hunk of foam material or something similar on which his whole body can lie. Then cut out a patch where his butt could rest kind of suspended from pressure.
Judy will happily volunteer her Tempurpedic mattress for the experiment.
Then you can name it something cool and make your fortune.
Wonderbutt?
SweetCheeks?
Buttless Wonder? (that's what I call myself, for I have none)
Butt-on?
Your***Hole?
Rearview Manger?
BreezyBuns?
The possibilities are endless!!
