Devil, I rebuke thee (angelic smile)

The difference between my LG wife is that if I were to *ahem* inside her...or....on...her........*ugh* she would just take a bath or a shower and be clean (in a physical sense and in a Biblical sense too :)).
She could then play with other little girls without the fear of getting any *ahem* on them.

But cloth tends to retain stains and germs longer and better than skin.
How many times do you think they wash hotel rooms and still they find stains with black lights all over the place.
(A weak evidence I know, it begs many questions, but it's mostly there for comic relief :p)

Anyway, that's the difference, in a nutshell.
