Yes, I'm an extreme urine-o-phobe. Definitely related to my OCD. I'm not into jizz, other than feeling what I assume is an evolutionary sense of rightness from jizz in my vag, but jizz isn't dirty in my mind. Urine is a waste product and thus one of the filthiest things imaginable. I'm not a germaphobe so microbial sterility is no bonus.
I'm glad we agree on the shower. Of course what people do in their own homes is up to them, but to pee in someone else's shower when you're a guest is just incredibly uncivilised and downright rude.
LOL, jancrow! No, I'm still far more terrified of urine. I do realise it's not rational. Shoes and handbags horrify me, too.
