Have her look at the Kinsley Scale. I consider myself a 4 on the scale, and it seems the way you describe your friend to be. Maybe you could read my recent thread about my orientation. http://forums.psychcentral.com/showthread.php?t=130173 People are not just black and white, there are gray ones too. What I mean is, people aren't just straight, bi, or gay. You may also have her look at photos of male celebrities that most women seem to be attracted to, and then female celebrities. She may just be extremely picky with men. She may have only a certain type she is attracted to. If that type seems to resemble her boyfriend, it may mean that she is just in love with her boyfriend mostly for who he is as a person, not exactly as a man. I have learned from my past that I was only attract to my ex-boyfriends when I was dating them. And now I'm only really attracted to my husband or people that look similar to him. However, I was and still am always attracted to women.
