Hiya! <3 Yeah, it's my clueless ol' ass, inadvertently derailing things as per usual! With you gently but firmly guiding me back on track once again :)

So, by way of apology, allow me to be the first to answer the question posed in your actual post!

What stands out for me, in retrospect, probably is the "first inkling" that I ever had: seeing Raiders of the Lost Ark at age 13... and being attracted to both the male villain AND the female lead. (Yeah, I thought that Harrison Ford was pretty damn fine, too, but somehow bad-boy Rene Bellocq was the guy who really made an impression on tween me.)

Though I didn't appreciate it at the time, this amounted to Bisexuality: Condensed Version. Especially when these two characters/actors appeared together in the same (often sexually-charged, what with Bellocq lusting after Marion) scene! Bonus points for how, even at this early stage, my long-term pattern of being drawn to each sex in quite different ways (women more physically, men more emotionally) was already present.

About me, demographics-wise: female; GenXer; USA.
