Sometimes I cant tell when I need to go

I pretty much been Diapered 24/7 but not wetting 24/7 for 3 years now. For the first 2 years I was mainly wetting when i was home from work and bed time since i was working days. Since I been overnights. Soon as I get home from work no potty for me accept for pooping.  There is times I cant tell  when I need to go potty. Its like I don't feel the urge to go and can tell its happing in my diaper. THere also times I did not realize i went and my mommy/wife checks me and say your wet. Sometimes I been waking up wet as well. Also several close calls in my pull-ups. I guess after 3 years I finally loosing some control
