You can change her alignment to True neutral.
No no, I'm talking specifically about her habit of teasing you with "I know you want me, pet ...eh I'm getting bored, leave me be." dialogs.
If you wish to indulge in that kind of things, I'm sure there will be plenty of fanfics and mods.
But I don't remember anything like that in the vanilla game no, the romance was pretty much the usual Bioware style.
