We were learning salsa in class and the guy is supposed to keep his hand on the girl's shoulder blade during the basic step. But we'd do a different step and come back to the basic, my partner's hand would always come to my waist (I know it's probably just more natural to put it there) but it made me wonder if guys ever think about touching a woman's waist, if they like it, or if it ranks up there with like boobs, legs, or ass?
It is a sexy part of a woman's body. And it is some way between being overtly sexual, and being completely platonic. So for a guy who's not dating the girl, holding her waist is a new level of intimacy.
I think there is something about a waist that can be sexy because on a typical universally attractive curvy type of frame, the waist is the smallest part of her frame, the larger hips and breasts emphasize the waist and it creates a sexy silhouette and shows off all her curves. Women with a certain waist to hip ratio are considered attractive, meaning a certain difference between your waist and your hips, that your waist is significantly smaller than the hips.
