I have fielded a question or two about my sexuality, in recent light of the Hermetic's Rant: Gay Marriages node.
This is my answer:
I consider myself to be bisexual. More accurately, I am politically bisexual.
I will sleep with anyone that I find sexually attractive. I have simply never found a man to be as attractive to me as any other woman.
I still feel flattered when a gay man hits on me or flirts with me. However, just as with women, I am not interested in sleeping with them if I am not attracted to them.
