What does pansexual mean? Bi-sexual is being attracted to BOTH genders, while pan-sexual is simply accepting that when you fall in love with someone, you will love them for them, and not care what the gender of that person may be.
Bi-sexual is attraction to both genders. I reality they're saying that people who fell in love with bisexual people do so because that person is not straight. That's dumb, I know bisexual people who fell in love with each other base on their personalities so the pansexual thing just doesn't cut it.
Miley was with guys and now with a woman so she's bisexual and can't tell no one that she's only a pansexual to get out of that one. A pansexual can be sexually and emotionally attracted to anyone regardless of their biological sex or gender identity.
It doesn't have anything to do with not caring how someone "looks", I don't get where people get that idea from. Pansexuals will likely still prefer attractive people like anyone elsebut they don't care if the person is transgendered or intersexed or genderqueer or whatnot.
