When I wrote of "sex without guilt," I didn't mean the guilt people may feel when they have sex outside of what their partner believes is a one-on-one relationship. I mean the association of sex with sin that's dominated western thought, manifest in such cultural memes as the fall from Eden; recurrent taboos on masturbation, homosexuality, or any non-procreative sex for pleasure; the use of the Anglo-Saxon word for sex as our most profane syllable; movie ratings that treat loving sex as more objectionable than hateful violence; and so on.
I don't see Kory as believing in or representing "free love." Kory values a one-on-one, committed relationship including love and sex as much as Dick does (in Wolfman's characterization, not Jones's). So when Kory's in such a relationship, she doesn't "cheat." I can recall only one example of Kory being "jealous" about Dick and another woman, but I think that's consistent with her belief in monogamy.
Indeed, I think the jump from my phrase "sex with love and...without guilt" to "Wee, sex is free and we should all just do it because we feel like it!" reflects our western culture's linkage of sex and sin. Is it possible to think of Kory as unabashedly enjoying sex with someone she loves without thinking of her as unabashedly enjoying sex with everyone?
(A better test might be to ask what Kory would do if she loved two people: would she be comfortable having sex with them both? The closest we've come to that is Kory's first marriage. She was definitely comfortable marrying one man for political reasons while maintaining her loving and sexual relationship with Dick.)
As for nakedness, we are talking about a mainstream comic-book character here. Within the constraints of the medium, Kory's as naked as you can get—so much so that DC had to change her costume for the anti-drug issues of the 1980s and the Teen Titans TV cartoon. What's supposedly her armor shows exposes more skin than Robin's costume, for goodness’ sake.
Now, does any of that change the fact that Kory is a fantasy figure created by and for heterosexual males, especially appealing to the unrealistic spotty adolescent kind? Not at all! Indeed, Kory's commitment to monogamy is even more of a fantasy fulfillment: she's not just a buxom, half-naked alien supermodel, she's totally devoted to her man!
