Alfred Kinsey, a famous sexologist from the 40’s & 50’s derived a scale for rating our sexual preferance based on our history.
Unlike what we still use today, that is, polar types of either hetrosexual and homosexual desires. He describes it more like this:

“Males do not represent two discrete populations, heterosexual and homosexual. The world is not to be divided into sheep and goats. It is a fundamental of taxonomy that nature rarely deals with discrete categories… The living world is a continuum in each and every one of its aspects.

While emphasizing the continuity of the gradations between exclusively heterosexual (0) and exclusively homosexual (6) histories, it has seemed desirable to develop some sort of classification which could be based on the relative amounts of heterosexual and homosexual experience or response in each history […] An individual may be assigned a position on this scale, for each period in his life. […] A seven-point scale comes nearer to showing the many gradations that actually exist”

So where do you come on the Kinsey Scale? I guess I am about a 2 from my history. Nothing perfect about me.
