two biological lovees which about 99% of us are in, there's a third (born with both genitals) but it happens rarely and because something forgeted up when you were being created, people with this trait usually have it sorted out at birth with their parents choice.
people who are transgender (went through things like hrt or surgery) should feel free to identify themselves with the gender they set out to be, but should be honest about it if they're getting into a relationship.
people who just say "my mind love is female/male!" should not be taken seriously as they're likely doing it for attention and making people with actual gender dysphoria/self identity problems look bad.
