I was thinking of the whole sex thing and how it's pretty strange how we humans basically like to release ourselves of fluids and watch as our lovers scramble to catch and lap it up (if we're lucky.)
I wonder what the Martians would think if they saw how much time and energy we devote to this pursuit. Speaking of Martians, how do you think they make love to each other?
Strange how fluid leaving one part of the body and entering another is the basis for exciting us- AND for the procreation of the human race...
