Miguel O'Hara is such an overly controlling arsehole, but something tells me he'd be very very very HOT to write steamy fanfics about.
I can imagine him being Deliciously Desperate for human touch and self-loathing because of it (he can't be attracted to anyone! People that he loves die!!!) and also kinky AF not because he consciously decided to be so, but his spider genes....fangs 'n claws, y'all. Cue more self-loathing because he's been brought up as Catholic. Mexican +Irish to be precise. It doesn't get any more hardcore than that.
(This is how it is. Once I get back to writing sexytimes, I start to notice the Sexy in all kinds of works of art.)
Look at this shapely mug. You can't tell me a man who tries so hard (and fails!) to come off an Emotionless in his daily life isn't a bubbling witches' brew of sexual yearning under the surface.
