Most likely the labels are beginning to show their inadequacy. The truth is that sexuality is a continuum; therefore, the question becomes: where does heterosexuality ends, where bisexuality starts, where bisexuality ends, where homosexuality starts. Do we really need to define ourselves before, during, or after a sexual encounter? Let’s just enjoy the intimacy as it comes.

Denial aint a river in Egypt. How someone identifies themselves publicly, is not always the way they would define themselves privately.

Why define yourself or another person. Putting a label on something or someone places an identity that may not really define them. Most labels I know of tell more of the person doing the labeling than the person labeled.

I can't help you... you are on your own there.

I believe you are describing "being on the down low."
