I have to get on all fours to pee. I am paranoid about leaking and often have a very strong erection at night so if I were to pee laying on my back it would simply run out the top of the diaper. I doubt I will ever be able to pee laying on my back so for me it is just the way things are. I am used to getting up to pee anyway, so now I just turn over in my bed, grab a pad if I am concerned about leakage and let it go once I can relax enough. I do find that between paranoia about leaks and the very soft surface of my bed it is harder to pee in bed than if I get on the floor, but eventually I can relax enough.
I am still working on a proper nighttime diaper for my needs. As I said I found that bulk in the back is uncomfortable and I like to mess my diaper in the morning so I am beginning to think an ATN with a booster in front will work well for my needs. I will find out tonight as I am prepping for a colonoscopy tomorrow and so plan to wear a diaper to bed tonight and be diapered all day tomorrow. At least that is the plan right now. I am hoping that liberal amounts of A&D ointment and Coconut oil will keep my skin in good condition...
