Imoen's sexuality, Hetero, Homo or Bi?
That's a good question.
Imoen has always been playfull and curious, she was always where she should not be, doing what she should not do,... She read Gorion's letter, followed you without permission, ... and as chaotic good thief, she certainly does not care for society, chaotic god people dislike conformity social conventions.
As was said, it's very likely that no homosexual encounter were added to the game because it could offend people, not a good thing for a buiseness. Taking into account that Imoen showed no real interest in any of the genders, and that the devs would not label a character as homo or bisexual, could it be that they didn't add any proof of her sexuality because they created her bisexual, but could not say it?
Personally, I see Imoen as a very curious, open minded and playfull character, so I'm pretty sure she would be willing to try lesbian sex at least once, this could or could not be with the PC and it could or could not happen, I simply see her as willing to try it, if the opportunity presented itself.
How do I see her? It's a little hard to explain, so I'll give an example:
Let's say she is walking with the PC in the cooper coronet, I see Imoen as the kind of girl that would not mind saying comment like "Wow! Look, CHARNAME! See this girl! Don't you think she's cute?" or "Wow! Look at her! I bet you're having naughty thought right now!"
And according to the 2 banters that were discussed earlier, it's obvious that she like being complimented, and indeed, who does not like it? What would happen if a girl made the same comment about her? Would she be offended? I don't think so.
So, in conclusion. Hetero, Homo, or Bi? Well, I see her as either a very open minded and possibly bi-curious hetero, or as a bisexual leaning a little more on the Hetero side.

Ok, this is unrelated to my post, and a little of topic, but you said in this thread that Imoen did not get raped while being Irenicus's prisoner. Well... when you first talk to the 3 dryads and Imoen is close, she will say her "Wow" So beautifull!" comment, (Which also prove little my point of her being open minded) and in the discussion, the dryads say something like: "Poor girl, he touched you like he touch us..." to which she reply something like "He is so cold, he is getting no pleasure" and the dryads reply something else. Just redo that part of the game if you want the exact quotes, my game is uninstalled, I can't look.
Also, when Imoen say that he did the same thing to her than he did to the pc, well, he did torture her, and who's to say a female PC did not get raped while prisoner? I think Irenicus would do anything for his litle experiment. Probably even raping a male. He seem willing to get "dirty" for his ideals.
So, did I miss something? When you say she was not raped, do you have a good source? I'd interested to know.
