<p>Chart of sexual orientations, showing how the terms "gynephilia" and "androphilia" slice the possibilities of male/female attracted to males/females in different ways than the terms "homosexuality" and "heterosexuality".  A "gynephile" is someone attracted to women, and an "androphile" is someone attracted to men.

The interpretation of the chart is that a person who falls into one of the four quadrants of the chart can be called by any of the terms appearing in that quadrant (except that you have to be categorized into both cells in a column to be called "bisexual").  This graphic does not show logical/semantic subset or inclusion relations, and so is not a Venn diagram.  The interesting point is that opposition of "gynephile" vs. "androphile" divides the four cells of the chart by rows, while the opposition of "homosexual" vs. "heterosexual" divides the four cells by diagonals.
