Hi Sparkcat. I don't post a lot because I am a hunt and peck type typer. I agree with Skeezyks about finding a good therapist.
I suffered from what some label as bisexual conflict when I was a young man. I was lucky to work with a good psychiatrist at that time. This was in the mid 70's when the gay liberation movement was in high gear in SF where he was located. He used Freud's theory to structure his practice. He told me once that all a theory is, is a tool to structure your work by. He helped me get things in perspective and to not take things so seriously. I told him about being taken to church every Sunday when I was young.
He told me to remember, cleanliness is next to godliness so make sure and use a condom.
For what it is worth, I recently saw a documentary on our primate cousins the Bonobos. This one researcher stated that bisexuality was kind of a way of life in the troupe. He when on to speculate about human sexuality. He thought that there was probably a lot of heterosexual people and homosexual people who may actually be bisexual but because of societal pressures they migrate to one group or another. That was his theory any how.
I don't know if this helps you any or just makes you more confused. Anyway, like Skeezyks said try and hookup with a good therapist. That old psychiatrist sure helped me sort things out.
