Which confused me, because by then I knew that I was expected to be straight, no two ways about it. I knew I was utterly heterosexual. Then, for a while, I thought I was a Lesbian. I was straight and women were my kink. I got serious about things and did some research and found out that there were bi guys, bi couples, that you could be in a serious relationship with a woman and still like guys, and that you could be in a serious relationship with a guy and still like chicks.
Bisexuality is a choice.
Someone who will be reviled by Heterosexuals because I am not straight, and by Lesbians because I am not Gay. No, I didn't choose this. Sexuality is not a choice, I cannot stress that enough. You can choose partners, but have no influence over gender. I was born this way.
