I've been dating the same woman for about 3 years now. I really want to open up to her about how I like seeing her pee. She's somewhat open minded, but pretends to be prude. I don't know, it's weird.
I have no interest in peeing on her, but mainly just want to see her pee in naughty places and (maybe) piss on me in the shower.
She already let's me in the bathroom when she pees and let me wipe her once (I didn't ask, she jokingly told me to do it).
What's the best way to open up to her about some mild pee related stuff?
