Your sexy? Hm. For me it would be having an obviously female phenotype (curves and big tits) combined with many stereotypically male behavioral traits including "doesn't take shit" combined with the fact that you think I'm hot and you (used to) get flustered. A kind of sweet-and-innocent look combined with shocking depravity.

My sexy? Hm. Being obviously male combined with some deliberate gender subversion, scary, competent... hm I guess "transgressive" sums it up. That's the bait, but the hook is being sweet and sentimental. :)
