I guess this is a different, and far less satisfying, form of "edging".
Even the completely legit places litter their ads and websites with pictures of doe-eyed young thangs with unnatural cleavage and curves, tossing you a "come hither" look through photoshopped peepers. Once you have gone thither and through the door, you're unlikely to leave until the absence of dream fulfillment has become obvious. Painfully obvious, in the blue-balled sense of the phrase. At least the first time.
