we've gone over this before: Gender is not what's "in your pants", neither is sex. Whatever genitals you're born with defines your gender, whether that be a cock or a pussy. I still don't understand why people are bringing sex into this because it's literally used in the exact same way.
Your sexuality options, aka your SEXUAL ATTRACTION TO SOMEONE, are either STRAIGHT (attracted to the opposite gender, and set as the default setting from birth), BISEXUAL (attracted to both genders regardless of what you were born as), and GAY (attracted to the same gender you were born as)
There is nothing MORE, and nothing LESS than that.
