Everyone with a sex drive wants sex, but they want it from the right person. The heuristics surrounding the "right person" selection process have been destroyed. The women I know who have retreated from dating have almost unanimously expressed frustration with both the poor selection of available men (because their standards have been artificially inflated) and the constant push from the available men for the women to engage in casual sex (the men no longer have meaningful and safe road maps for how relationships should progress).
