Legs appeal to multiple senses: sight and touch. There’s a superb shape and line as well as an enticing texture (enhanced, of course, by shaving and perhaps nylons). At the sight of a woman’s legs, a man might well dream of running his hands over them and coming between them. And that smoothness in turn suggests and evokes what? So it’s no “accident” at all that shaving and wearing nylons are cultural enhancements that even more strongly allow legs to evoke feminine sexuality and enhance female sexual power.
With clothing, legs can also very handily be both revealed and concealed, which makes them almost uniquely empowered to allow women to tease and seduce men and inflame their imaginations. Legs being long, a little can be revealed, then a little more, then …. and so on, all the way up. It all depends on how much she wants to show. And sometimes less can be more. In addition, the momentary flash of legs through a slit skirt while a woman is in stride or crossing her legs can burn a potent image into a receptive man’s mind, both because they are beautiful in and of themselves and also because they suggest sexual availability. And if they are subsequently concealed, you yearn to see them again and also to see more. Dresses and skirts are all about advertising accessibility while also concealing and withholding.
In brief, a woman’s legs can at once please and tease. And while the partial display, or exposure, of a woman’s breasts or butt “function” more obviously in this seductive manner, it’s undeniable that for many men a pair of shapely legs alone have the power to effect this enthralled response.
