estro babe

A woman who has a very curvy hourglass shaped figure. To achieve this she must have in her system large amounts of estradiol, the principle estrogen hormone, as well as a good supply of progesterone, and low amounts of testosterone and cortisol. Marilyn Monroe, Sophia Loren and Julie Newmar had this hormonal make up and therefore had the shape that drives men wild.

I can't stop checking out the curves on that estro babe, she's like a drug.
