Chris is genetically a male. This is unquestioned.
Chris is also entirely interested in females as objects of sexual desire. If Chris has ever expressed interest in any genetic males whatsoever, I defy anyone to present evidence of this.
Therefore, Chris is a male whose sexual interest is entirely in females.
There's a word for this. It's heterosexual.
Chris is a heterosexual male.
Chris also has gender identity issues. Those are different. I am at a loss as to whether to call Christine he or she, but I am not at a loss as to calling Chris what Chris is, and that is a heterosexual male.
