Well, perhaps the reason, in your fantasy, you cannot get past fantasizing about kissing a woman, is because you've never gotten past that in reality.
You are obviously attracted to women. You just need to figure out if you are sexually attracted, emotionally attracted, or mentally attracted to these women. There is often a difference. For example, I am physically attracted to women, sexually attracted to men, emotionally attracted to only the person I am with, and mentally attracted to intellectuals.
Maybe you should get with your old friend and see how far things go.
Regardless, I don't think this is anything you should be worried about. It is perfectly natural to be attracted to people that you wouldn't normally find yourself attracted to, regardless of sex.
