A big part of the reason I like giants is because I feel like the smaller you are in comparison to them the less your gender or your anatomy even matters. Your chief defining feature becomes your size rather than anything else and that is super refreshing to me.
And in the case of giant robots, it really matters even less – your chief defining feature is “small human”, and like, “small human” is pretty much the extent of anything that I have that might be called a gender. (“Small, cute human” is more accurate tho.)
So in writing Body Check, even though it looks het at a first glance, I’m always trying to undermine that when I write Hound’s POV. What he finds attractive about Astrid has nothing to do with her gender or body parts – the mech literally gets off on the moisture in her breath, for example – and at one point he admits that “men and women both make the same sounds when they orgasm”, and that it’s tantalizing to him either way. Their difference in size, muscle mass, fat distribution, voice pitch, it’s all so superficial and minuscule to him. Humans as a species are small, squishy, fragile, and mostly water – and that contrasts immensely with his physical characteristics, which is what he’s into.
And what I’m into :V
