And one of the intriguing things about us, is that we have managed to eroticize just about every part of the human form at one point or another. This is true across cultural boundaries, and across the long span of our time here on this planet.
There have, naturally, been certain things that have remained relatively constant. For the greater part of human history, broad hips, a full bottom, and significant breasts, were the most erotically charged body parts for women.
Alteration, over time, of silhouette for women, and men, has contributed to this by artificially widening shoulders, nipping in waists, and broadening hips. But never, interestingly, all at the same time. Typically one or two zones are chosen for focus. If for example, the focus went to legs and shoulders, as it did in the 40s for women, then the hips were narrowed visually. If the center of attention was the neck and bosom, as it was in the later 18th century, then everything else was designed to draw the attention straight to those areas.
