I need someone to spell it out for me, since I'm told I'm blind to flirting. If someone asks me if I "come here often," I'm likely to sincerely explain that this my first time there, etc., then walk off.
My sister used to keep me in line, socially, covertly telling me if a boy was "handsome" since I couldn't tell that either. Luckily, in elementary school this wasn't an issue since boys typically sent their friends to ask my friends if I liked them or not.
Probably comes from my being an androgyne (mixed gender) demisexual (on the asexual spectrum; feels no lust except for one person at a time, and only after a prolonged courtship).
@AxeElf Dunno.
I could be XXY, or something like that, but, in accordance with Occam's Razor, the simplest explanation is that I was conceived only three months after my older brother's birth, so absorbed the male hormones still in the womb.
This occurs with animals, as well.
I'm the kind who would just say..."hey, are you checking me out" heh heh No need for a secret handshake.
