No, no, no. I know that for myself it is not, has never been, and will never be a choice. I tried to date girls but I never felt any real attraction to them. I knew from the time I hit puberty when I was about 12 that I liked boys, and here I am 10 years later living pretty happily with the most wonderful guy in the world. Never once in those 10 years have I been attracted to a single woman.
