Sexuality is a lot like an ecosystem: one change to one part of the system usually impacts other parts of it, and one tiny shift in one place can sometimes change the whole thing quite radically. And just like with ecosystems, the same shift in one system won’t always have the same impact as it would in a different one: the great diversity of people, our lives and experiences — and all of those pieces we’ve been talking about — means that sexuality is also greatly diverse.
