My missus said to me once 'Why do you have to piss in the shower..'
I told her it was hard not to when you are having a shit...
It is fine to do this then push it down the plughole with your toes.
I don't like it when I get near to a perineum of someone when having sex & find they haven't washed there. Therefore I appeal to all to do a handstand in the shower so that the water cascades over the offending area.
