Sorry, but now you are reducing the human person, male and female, to a sex object, male or female.  From cover to cover   in the Theology of the Body, human bodiliness is always referred to as male *or* female but human personhood is always referred to as male *and* female.  We are body-souls, personal subjects, rational animals; not simply biological animals.  This is the problem with the male-only priesthood: it reduces the human person to a sex object.  Doing so is heritage from patriarchal gender ideology, not revealed truth as explained in the Theology of the Body.  

See also my previous comment about XX and XY.  Biologically, the fertilized egg is always XX, then sometimes differentiates into XY, but human males and human females still share the same X, so we are fully homogeneous somatically of the same flesh), even though anatomically male or female (or, sin some cases, intersex).
