I am pansexual. I love people, men and women alike in every shape and size. I am also bipolar. I notice that my sexual preferences will lean to one gender or the other every couple years.

Pre-high school, I favored boys.
High school--I fluctuated up and down dating both boys and girls.
My first year in college, I was neutral and liked them both evenly
Now it's my second year in college and I'm leaning towards boys and now I'm fixated on trying to find a boyfriend, specifically to fulfill fantasies I have involving men. I rarely fantasize about women, but I do love women, but now I'm focused on men.

What's up with that? I'm not questioning my sexuality at all: I know I'm pansexual and I know I love both men and women, but why is it that I have swings of wanting only men or swings of wanting only women? Does this have anything to do with me being bipolar?
