I know this is a very old thread, I only recently have been using the Android Kotor but have had it on Xbox and P.C. I am only now using the mods and an editor for the game, but I set my character to be a rodian using the save editor and I put gender as "both" and i played through, not far but it seems that Neither bastila nor Carth will acknowledge your gender, neither will be interested in you (the gender usage was after the slave quarters at Daviks estate) I had only did the gender thing to see if it would effect anthing but it seems to be the same thing as selecting "no gender". Option works best if you want to for whatever reason cut off any type of flirting with ANYONE.
