My truth is that I am a gay American.

I engaged in an adult consensual affair with another man.

As a child, recognizing my difference from other kids, I went to the local public library to try to better understand my reality. Back then, many library card catalogues didn't even list 'homosexuality' as a topic.

The arc of American history almost inevitably moves toward freedom. Whether it's Lincoln and the Emancipation Proclamation, the expansion of women's rights or, now, gay rights, I think there is an almost-inevitable march toward greater civil liberties.

I've never been much for self-revelation. In two decades of public life, I always approached the limelight with extreme caution. Not that I kept my personal life off-limits; rather, the personal life I put on display was a blend of fact and fiction.

More than anything else I recall being, or trying very deliberately to be, a perfect child. Not a Goody Two-shoes, but a kid who did good, who worked hard and met every expectation. I strove to achieve in the excessive way that psychotherapists tend to regard with concern.

Because of an adulterous affair I shall leave office in November.
