If temperatures reach 600 degrees Celsius, a complete melt-down occurs: rocks become magma, which, when it cools, creates
igneous rocks, something entirely new. But during metamorphism, nothing is lost or added at the elemental level. The basic
composition stays the same, which is what is so complex about
it: that the rock can still be what it is and yet be in the process of
becoming something slightly di=erent. What I don’t get about
metamorphism, that the metamorphism takes place while the
rocks are in a solid state, is also perhaps what is so groundbreak-ing about new theories on human sexuality: according to Lisa
Diamond, it is possible for a person’s sexual desire to change
in the context of a single relationship while that person’s sexual
orientation remains the same.
Diamond has coined the phrase “sexual fluidity” to describe
this phenomenon. In her book by that name, Diamond addresses
how most people believe that the biological order of a romantic
relationship entails sexual desire first (that initial “chemistry”)
and romantic love (the intimate bond) second. But, Diamond’s research shows, the opposite can also be true, especially for women.
What begins as an intimate friendship can turn sexual. Di=erent
