Mm.. Please don't take this the wrong way, but this kind of reminds me of the old adage: "Sure you can catch an std from public toilet but it's a strange place to take a date." *gg*

More seriously, I guess we, modern humans, seem to have an almost annate intriuge with toilets. I mean look at how kids will always gravite to the toilet/toilets of new surroundings. It's something that we consider we "grow out of" but for many of us it's just something we repress because of what our society, generally, finds acceptable.
