Perhaps it’s not debased at all, but just another aspect of sexuality that is unique to human beings?
Let's see: I would bet a very, very, very small potion of the female population thinks a "train" is a fun night with the boys...?
Is that even considered "sexuality"
For something to be "debased" it has to have a baseline...as our culture descends into lower and lower standards, that baseline gets lower and lower..
Hard to believe at one time not very long ago, TV censorship did not allow people to sleep in the same bed or mention being "pregnant"
At what line do you draw to say we have gone low enough?
