Since more sexualities than just bi are being thrown about here, I feel like it's time for a comprehensive list:
Homosexual: a person who is attracted to the same sex/gender.
Heterosexual: a person who is attracted to the opposite sex/gender.
Gay: a man who is attracted to males.
Lesbian: a woman who is attracted to females.
Bisexual: a person attracted to males and females.
Pansexual: a person attracted to personality regardless of sex or gender.
Asexual: little or no sexual attraction to others.
Polysexual: similar to bisexual, but person acknowledges and is attracted to more than two genders e.g may be attracted to a female who is gender-fluid.
Demi-sexual: a person who doesn't feel sexual attraction to a person until they have a strong emotional connection.
Autosexual: a person who prefers masturbation and/or are attracted to themselves.
Pomosexual: someone who doesn't identify with conventional sexualities.
Androsexuality/Androphilia: a person attracted to masculinity, not necessarily males.
Gynesexuality/Gynecophilia: a person attracted to femininity, not necessarily females.
Queer: a person who is not heterosexual and wants to acknowledge it without conforming to a conventional sexuality.
Omnisexual: a person who does not have a sexual preference and may be attracted to everyone equally.
Then you start combining this with the gender identity spectrum and shit gets weird.
Don't like any of the ones listed? There are more! There will always be more.
If you like girls and guys, you can identify as bi. Or you could further specify your wants and identify as something else.
What also irritates me is this whole 'pansexual' word being flung around. As far as I see it its just a fancy term for bisexuals that have no idea who the fuck they are yet.
To me, that seems dangerously close to the whole "bisexuals are just straight or gay people who haven't decided yet".
Bisexuals are attracted to males and females because they are male and female. Yay for titties and dicks!
Pansexuals are attracted to people
regardless​ of what gender they are or identify as.
