Super straight
Super straight is a “sexuality” that people have come up with meaning that a heterosexual biological man will only date a biological heterosexual woman, or vice versa.

It is transphobic as if you were a man and saw an attractive woman (if you got the chance) you would go out with her but if you then find out she is trans you would not go out with her purely for the fact that that she is trans- which is transphobic.

‘Straight’ means that you would go out with the person of the opposite sex and if you were a man you would go out with women (this includes trans women.) But it is not transphobic to prefer biological women as they can have children and naturally have more feminine features (though transgender people can have the same) - this still means that if you were attracted to a trans woman you would still be attracted to her despite them not biologically being a woman. It becomes transphobic when you will not go out with the person of opposite sex purely because they are transgender.
