Queenbea, your post really struck a chord with me. Thank you.
So, I define myself as bisexual to take the stigma out of the term. And that's what it is when you think about it, a term. And if you care to think about it as a more than or a less than is your individual choice. Personally, my story is that I had a short relationship with a woman in college (I am now 32). I was brought up strictly religious, so I didn't follow through with woman for a long long time. My whole life, I've had relationships with men, and been actually in love with three. I only enjoyed sex with one, (my latest guy), because prior to him I thought men's giggly bits were gross and disgusting.
Now, I just recently broke up with a girlfriend. We were together for two months, and it felt right. I decided after dating some guys that I really wanted to try women again. Ultimately we were not a match, personality wise, but I was falling for her. And I fell for her fast. (Not scary fast, but fast by my usual men's standards.) So, now, I'm not really sure I want to go back to men. I'm not ruling it out totally, but I'm actively only searching for a woman partner. Now, I am a monogamous long-term relationship type of person, that just happens to identify as a bisexual. I don't think I could even rule out dating a trans person in the future. It is sort of strange, because I now feel strange about my past romantic and sexual relationships with men, even though beforehand, I could have sworn I was in love with them. But, I believe that sexuality is fluid, I guess. Otherwise I would have no other way to describe my experience.
I do know that I love women-romantically and sexually (totally). I love women's bodies, and everything. So, there's my story. And I'm stickin' to it. For now...
