Or of transexuality, the line reminds me of Ozma's "I'm still the same old Tip you know."

Though of course Oban's desire to continue the relationship doesn't gell with the trill laws introduced later (but that's okay).

Jaddzia was shown to be pansexual, in more than the one episode... There was a lot of hints of her having interest in other women, there was the erotic pottery scene on Riza where Worf gets jealous for example.

And I don't think it's just because she's a joined Trill, it seemed to be very much a part of who Jaddzia is (though in the early bits of the first season she made references to joined Trills often being chaste and implied she was, so who even knows).
