i agree with @
FlyingJesus;, you can only be bisexual because there are only really 2 genders to be sexually attracted to (intersex is a mix of two genders but you would still fancy an intersex person because they look male or female and not alien). it's funny that bisexual people are thought to be transphobic and pansexuals are high and mighty because they "also fancy transgenders" which is transphobic in itself because transgenders ARE male or female. sure some bisexual people may not want to date a transgender but do we have a seperate sexuality for straight people who don't want to date transgenders of the opposite sex? lol
it's hard to explain but it's kind of annoying to be called transphobic when we're the ones that acknowledge there are only 2 genders, not male, female AND transgender. people are biologically male and female, you're attracted to their looks, not what they identify as, so that includes transgender, agender and genderfluid.
