It seems on every diaper i try the padding ends right at the top of my but and ends and it never felt right. Is it just in my head or should they rise higher up the back?
Most diapers seem to have the padding stop a little early for my perference, in the front and in the back. Some of them add several inches of what I refer to as "dead plastic" on the front/back, where it's just shell and no absorbent material.
While I like the padding to come up a good distance, I don't care for the dead plastic. So with diapers that don't have an elastic waistband, sometimes I'll trim off some of the dead area on the front. (can't really do that on the back because you'd remove the top two tapes) XP Medical's Absorbency Plus is the one I do this the most with. But the AP diapers have a pretty good rise on their padding too. Or maybe they just run really large on me? *shrug*
The seal made by the upper tapes of the diaper should form a leak proof barrier against fluid escaping out the top of the diaper. If there's padding under this "belt" then that padding will wick moisture beyond the seal and cause a leak. Pad yourself accordingly. That "dead plastic" serves a purpose. Of course, if the cut of the diaper causes that seal too be to low in front for your erection (if male...), then you might find yourself uncomfortable, find a product that is comfy for you. In back, the padding height doesn't matter as much (unless you need more absorbancy there) as long as the seal is made.
