@TakoAlice8 It has varied over the years, and even now different moods take me down different paths.
When I started out, I would take two or more existing characters, either fictional or real, and imagine how they would react to encountering size differential. It wasn’t always interesting; I knew from the beginning not everyone would get into it as much as I would. Sometimes, however, it got exciting when the size differential revealed something previously unknown about a character (but if it diverged too widely from what was already known, it would break the spell).
Later, I would start with a particular situation or activity that would be more exciting with the addition of size differential, and I tried to imagine what kind of person the characters would have to be to make it happen. At first, of course, it was laughably transparent that I had invented these characters simply to engage in the desired scenario, but I came to appreciate that more complex and fully-realized characters having plausible reactions that eventually lead to sexytimes was more satisfying, and watching “normies” take a journey into size kink was as exciting if not more so than characters who were ready for sizey sex right out of the box.
As I started molding these ideas into narratives, it became clear that the social context of size differential would have direct implications for individual characters’ attitudes towards people of different sizes and their presumptions about what kinds of relationships are permissible (or possible). Is size difference unheard of and fantastical? Is it common and well-understood? Is it a natural phenomenon, such as whole species that are differently sized? Does it happen by a known process or for a specific reason? Does it have a random cause, like catching a virus? Are tiny people considered low-status? Are giant people considered monsters? Answering these questions helps form a baseline from which the characters are conceived. If cruelty to tinies is the norm, then it doesn’t say much about a particular giant if they treat tinies callously.
I cycle up and down this scale of complexity depending on what I’m in the mood for. Since sizey thoughts are always lurking in my imagination, my mood for complex or simple fantasies can differ from hour to hour.
