There is a thin wall in between the two bathrooms in my house. I have often thought that we could just cut a hole in the wall and hold hands while we both take loud shits.
When I was married, I was really turned off by the sight of her on the toilet. If it was accompanied by an odor, it shut down my sex drive altogether
It's even worse. The houses here are so close together that I've heard my neighbor pee and I've smelled his poop when he left the bathroom window open.
When I was dating my first wife I used to go crazy for anal with her, down for that anytime all day all night, she never required lube.... then we got married and she would leave the bathroom door open while taking a shit. After that I stopped having anal sex with her unless we were both really drunk and she asked me to put it in there.
