I find that in my enjoyment of size content, the quality and skill of the work matter more to me than whether or not the male porny gaze is obvious. And it is obvious, of course, but that’s fine. If it’s well done, it’s still hot.
Someone else said, their first audience when they write is themselves. I am the same. I have various hobbies, size writing being just one of them, and there are periods (like right now) when I’m not actively working on my macro writing. When I get back to it, I feel drawn by like this call that, “more hot stories about M/f giants have to be written - it’s still so underserved!”
In my M/f stories, I am writing for the sake of the people who see themselves as tiny women first, because that is usually the way I relate to these scenes, and, because I love encouraging tiny women to get more into it. I am glad that straight men enjoy my content as well, it’s always nice to have one’s work appreciated.
There have to be more women out there with this kink, who would be the ones who write less male-gazey-erotica, but I think a lot of them get instead drawn to the realistic-giant size range that’s well served by popular erotic fiction about werewolves and sasquatches, and call themselves monster fuckers, instead. If you’ve ever asked “Where are the women macrophiles”, my theory is, that’s where.
