Bisexual now, gay later?

According to Kinsey, sexuality is a very fluid scale that can variate at any given time during one's life. According to him, very few people are strictly hetero, or strictly homo. We're all a lil bit of this and a lil bit of that depending on the season, time of day and type of liquor. (ha)

So i'm wondering if i'm a poster child for the Kinsey scale.
As a child I was a child. Not really sure what anything was or wasn't, but I was awfully curious about both girls and boys. As a teenager I was into guys outwardly, and into girls inwardly but I didnt claim to be bi or anything. (Who did that in jr high?) As a young adult I began to question how straight I really was while I was thoroughly enjoying my experimentation with women. When I decided to finally drop the straight-mask, I immediately opted for bisexuality instead of claiming to be a lesbian. For some reason, it just sounded better. And maybe, at that time in life, I was bi I guess. But I knew something was wrong. And now as a grown, fully independent woman, I am a lesbian. Don't do men at all and don't ever plan on doing them again. The term bisexual no longer appeals to me in the slightest and now, I don't see how it ever appealed to me at all. But hey, it was what it was.
So how's that for a sliding scale? Is that a typical experience? Did any of you start the trip towards figuring out your sexuality, but detoured at a bisexual rest stop for a minute, before continuing towards gaydom? What about going backwards? From fully gay, back to bi? (Is this even believable?)
