The received wisdom in straight culture, is that all of its different norms line up, that one is synonymous with the others. If you are born with male genitalia,* the logic goes, you will behave in masculine ways, desire women, desire feminine women, desire them exclusively, have sex in what are thought to be normally active and insertive ways and within officially sanctioned contexts, think of yourself as heterosexual, identify with other heterosexuals no matter how tolerant you might wish to be, and never change any part of this package from childhood to senescence. Heterosexuality is often a name for this entire package, even though attachment to the other sex is only one element. If you deviate at any point from this program, you do so at your own cost. And one of the things straight culture hates most is a sign that the different parts of the package might be recombined in an infinite number of ways. But experience shows that this is just what tends to happen. If heterosexuality requires the entire sequence, then it is very fragile. No wonder it needs so much terror to induce compliance.
