(Since yesterday’s breast question went over gangbusters)
Speaking particularly about the curve in their waist:
1. It’s cool. Men don’t have it.
If men have any transition in their waist, it’s usually for the worse: a beer belly. Flab. Which is unattractive, and something for the eye to avoid.
But on women, a waist curve is as sleek as a line on a Ferrari. So, artistic.
And functional: it’s a transition between wider breasts and hips, two of our favorite places.
2. As a pivot point, it moves when she moves.
We keep an eye on that, being natural-born engineers, to see if everything is working properly.
3. Because, curves.
Can’t really explain it. It’s like asking why roses are pretty.

For our next anatomical discussion, the Women’s Movement:
I’ve always enjoyed it, especially when viewed from behind.
I agree, you can’t leave that behind.
I read an observation the other day that struck me as profoundly true: men’s vision is based on movement. That’s why women have so many jiggly parts.
“If I say you have a curvy body, will you hold it against me?”
Why? Why not!?
Playboy once reported on a scientific survey taken world wide. It found that the waist to hip ratio of <= 0.75 was universal in men finding a woman attractive. Boob size being attractive varied world wide (in some places men like them big, others, small) but this ratio was universal.
So YOU’RE the one who read Playboy for the articles! I was sure you were a myth!
Mmmm…. female waist…..
Not just me. Congress used to fund translation of playboy into braille. I recall the article I read about congress cancelling the funding for it. And it did mention that the blind were the ONLY group that could confidently be said to only read it for the articles.
