In my youth, I attended church three times a week. Went through a period of time where I actually tried very hard not to think of any "unpure" thoughts. So I just didn't talk about it with my mother or girlfriends.
So for me, talking about my sexuality with my therapist has really put me in touch with my core "needs". And it helps that I am in my 50s, I can look back on a lot of experiences. So by thinking about those past experiences and being more in touch with my current feelings, I know what I need and want. I think of it as one of the few advantages of being older.
So if you are still single, I agree with Bluebicycle that it is OK to experiment (safely). And it's good to talk about it with someone. As far as BP traits go, BP probably doesn't change your core sexuality but instead just makes it more likely that you go out and get what you want.
