I don't think a character who is sexy and enjoys sex needs sex as a part of every storyline
I can think of one scripter who's tried to play up other aspects of Kory. In his Teen Titans run, Geoff Johns highlighted her straightforwardness—criticizing Superman, learning to lie—and her nostalgia for home. Beast Boy made some leering mentions of her sexiness for old times' sake, but Kory wasn't in a romantic relationship, and none of the other principals of that book dared to start one.
But after a while Johns realized he was making Kory nothing more than a strict camp counselor for the kids, with no plot of her own, and he gladly sent her off to the Outsiders. Where, I guess, she could get enmeshed with Dick and be fully sexual again. It was, after all, an adult book.
I don't think a character who is sexy and enjoys sex...doesn't really have to look like kory.
Such a character in superhero comics would have to look sexy, though, since characters through their looks and costuming embody their defining ideas and qualities. Does "sexy" mean curvaceous, big-eyed, big-haired, and half-naked? Well, that would get the plurality of male votes. And, as you say, males seem to dominate in this precinct.
