That could be because tales related to Cupid and Psyche didn't evolve into tales involving sleeping women, as far as I know, but it is jealousy that starts all of the conflict in Cupid and Psyche.
Psyche is so beautiful that people refer to her as the second Venus, causing Venus to become jealous and order her son Cupid to cause her to fall in love with "the poorest, ugliest, and vilest creature alive." An oracle prophesies that she must be left on a mountain for "a winged snake, a monster so fierce that even the gods are afraid of him."
But just when things seem to be going well for Psyche-she loves her husband, has all her needs met during the day-her sisters come to visit, and out of their envy (although this time of her situation more than her beauty, but we can pretty much assume her beauty had to do with Cupid's falling in love with her) they decide to pressure her to look on her forbidden husband, inciting his anger. This she does, and because of that Cupid leaves and she is left to suffer and accomplish impossible tasks for Venus. She does this through the help of sympathetic creatures and eventually gets her happy ending.

And while I don't agree with that statement, it is true that extremely beautiful women have a unique set of issues (not that I claim to know this from experience. I mean I have good self esteem overall but I'm under no delusions). Men might go after them, but only for their looks, and other women do tend to be jealous. Beautiful women also tend to get stereotyped as being less intelligent and more shallow.
