you should massage his bladder when its full. see if he is willing to have sex with his bladder really full. how good is he at holding? see if you can get him to cuddle with his bladder full. 

True. I don't believe in using diapers or depends. Pee pads are ok because they can overflow. I have a severe fetish in bedwetting, dirty pissy briefs and of course I will wear someone's piss soaked underwear.

What I'd give for hubby to have a foot rubbing fetish 🤤

Hubby gets larger then life when he has to pee, it's cute and intriguing!
