@i-am-insane I’m glad you brought up Monster Fuckers. It’s an almost mainstream kink among women. I’m a monster fucker too.
My pet theory is that many women who feel a similar subby fantasy attraction that male giantess fans feel, bring that fantasy into monster fucking instead of human macrophilia, for whatever reason. (Maybe because they come across tall men a lot in real life so they find that not particularly exotic? And these tall men were shitty or just mediocre partners? Just spitballing).
I think that if someone made a site or a convention for both mf and macro, and it got popular, you might find a big overlap between macrophile men and monsterfucker women.
Unfortunately most of the people at this theoretical convention would be subs in search of doms, but that seems like a universal trait of kink communities.
