After living for years with an old toilet that had a mild sewer stink coming from the bowl, I learned to put both the lid and the ring down. And if you go to take the dump, that way the whole toilet won't reek like... you know, shit.
lid down, ring down
I'm married and I have pets
Mine isn't an option so I'll put it here.
When you leave the toilet do you: Fap, jizz into toilet, have a cig and leave the shit cause I'm the only one here. Besides my dogs love to drink that shit.
Lid down, ring down....because I'm a bit obsessive compulsive about these sorts of things.
