Using the penomat

I did some searching but couldn't really find anything than what people should get... Penomet or Bathmate!

But I am looking for pre penomet and post penomet sessions...

To use the penomet, I fill it with water, get my erect, then insert into it, right? Then pump the piece into my body to create greater suction? Then I sit there (while maintaining a full erection) for 10-20 minutes? Use warm/hot water?

Well, first time using didn't go well... at all. I did some pull stretches, filled up the bath in warm/hot water and jumped in. Filled the penomat up with water, pressed it against my pelvis (penis inserted obviously) and watched the bubbles fly as I push out water in place of myself. 11 minutes later, I stand up, it falls right off and I look exactly the same. So I figured i'd see if I could just fill it and make it stay, nothing. It just slides off. I am clean shaven, so that shouldn't be the issue. But, is everyone's gaiter totally flat on the bottom (part that meets your skin)? Mine is slightly angled, almost as if it was on purpose. Another words, if I try to stand the penomat up, it will just fall off. The bottom part is not straight.
