Sleeping with butt in the air, is this normal?

Over the past couple of months I've noticed some of my males, on random days, sleep with their butts in the air, I thought it might be a problem with their hemipenes or something wrong "down there" but there never seems to be even a slight problem.
It doesn't seem to be debilitating, but just uncomfortable, and suggestions?

Is he in the humid hide? I noticed some of mine will also raise their butts after I mist their humid hides. Perhaps they don't like their vent area resting on wet stuff.

haha, yeah, they are always in the humid hide when they do it. I guess you're right, they just dont like their "junk" on moist bedding...haha.
Just a funny observation.
