But first, to define some terminology: "Gal" is what I'm saying since neither "woman" nor "girl" is as age-nonspecific as "guy". Please ignore whatever patronizing connotation you may think "gal" has.
If "gay", "straight", and "bi" aren't specific enough for you, then consider "gay" to be kinsey 5-6, "bi" to be kinsey 2-4, and "straight" to be kinsey 0-1.
There are limits to the number of choices any poll can give (especially on LJ), but not limits to the number of different answers that are actually possible, especially with a charged question like this. Please, wherever possible, choose the closest answer even if it's not perfect. Feel free to elaborate in comments.
Now, then:
There is such a thing as a guy who's actually bisexual
If there were a new guy in one of your social circles, and he identified as bisexual, he'd really be
If a guy in one of your social circles is really bisexual, he'd most likely identify as
There is such a thing as a gal who's actually bisexual
If there were a new gal in one of your social circles, and she identified as bisexual, she'd really be
If a gal in one of your social circles is really bisexual, she'd most likely identify as
(As always, LJ lets you edit your poll results if you misclicked or something.)
