Seriously, I'm kind of annoyed with all of the comments in this thread that immediately assume bi chicks are more promiscuous and/or willing to have a three some.
Hear hear.
I'm going to be blunt, and quite possibly harsh to boot, because someone needs to say it.
Her sexuality has nothing to do with trust - it's rather ignorant to assume that because a person is attracted to both sexes that makes them less morally sound. Downright bigoted, actually.
I'm rather perturbed at both sides of responses here, the:
1. Bisexuality is bad, you can't trust them, and that's alright just find a "normal" girl, and:
2. Bisexuality is great, you'll have plenty of open sex with multiple partners if you so choose.
**** off.
She is a person. It doesn't matter who or what she's attracted to so long as you're the person she chooses to be faithful to. If you have trust issues with her because of who she is rather than what her actions are, you don't deserve her, and the problem is with
you.
And while refusing to date a girl because she's bisexual doesn't make you a homophobe per se, it certainly makes you an ignorant tard... six of one, half a dozen of the other.
My advice? Stay away, because you're the problem with the potential relationship, not her.
