Vore & Giantess
I'm thinking you were probably hoping for some little and giantess stories, but I actually make this fetish content and get paid really well for it, so I got excited to just talk about it! Sorry in advance if this is not meeting the challenge in the way you were hoping.
It's not a personal fetish, but it is a very interesting one to me. Any fantasy type of fetish is really intriguing in my opinion because of the implication of escapism entering into any fetish or kink.
In my experience with being a SW content creator, a large majority of folks' kinks stem from some sort of trauma (big or small), sometimes without them even realizing it. I think that opens a very wide conversation window that needs more exploration outside of academic circles if we want to create a more open and comforting environment for our intimate partners. Sex and erotica is such a taboo topic that many of us aren't even comfortable actually discussing it with our life partners, and sometimes exploring these fetishes and kinks is the most healthy way for someone to work through traumas and not act on intrusive thoughts.
