sort of a recap in my own words, a trillion years of bio-engineering, and we are the result. Women see reality through an estrogen filter, men see it through a testosterone filter. And if you think those drugs/hormones don't make a difference re-read this entire thread. Men have no choice to be driven. To the degree that we can be conscious of who and what we are we might begin to have a say over how we get there but we are driven. (sex drive) BTW, there are, of course, many men and women who have found themselves with varying amounts of said hormones, too much of one, not enough of another who completely blur the gender lines. And lastly, I agree, it's a control thing re: Pinups. One doesn't have to ask Vicki's permission to make her breasts morph to 11.
