I think perhaps more plausibly the reason that you don’t see straight cruising sites analogous to gay cruising sites is not due to straight women’s alleged distaste for sex (except for whores? erm. Yikes.), but that a straight woman who wants to get laid can go to a thing called a “bar”, where there might be “dollar kamikaze shots” and “men ripe for the plucking” and “music to which to wiggle.” O the peculiar mating rituals! There aren’t straight cruising sites because there isn’t a straight closet.
