I don't to seem to have ever had a problem going potty in my diapers, whether laying down, sitting or standing. Until 17 I woke up every morning in wet diapers and usually had no recollection of wetting them during night. Sometime I would wet in the evening before going to bed sitting with my sisters watching tv. Decades later, I still wet my diapers several times a day, sometimes while standing doing chores around the house or just walking around stores or hiking with my SO. Always potty in my diapers watching a movie or tv, or driving or having dinner at a restaurant. Love to wet my diapers while lying down in bed, or lounging at he pool, or just resting my head on my fiancee's lap and feel my pee running down my pee-pee and pooling between my cheeks.
