Contemporary debates about sexual ethics are dominated by a consent-oriented approach—consensualism. This position well explains the immorality of such acts as rape, pedophilia, bestiality and necrophilia. However, consensualism faces difficulties when it comes to adultery or HIV transmission. This article analyzes such unacquired moral obligations not to engage in consensual sex. A new natural law approach is proposed to explain and justify these obligations. This position places central importance in the evaluation of sexual acts on whether they are aimed at (...) achieving some common good and whether they harm some other good. As will be shown, the new natural law overcomes the difficulties of consensualism and grounds unacquired obligations in sexual ethics. And if this approach is combined with a pluralistic view of the goods that are realized in sex, then the new natural law does not allow the conservative conclusions about sexual morality inherent in the old natural law theory.

In this essay, I outline fundamental anthropological and moral principles related to human sexuality and gender identity and then apply these principles to analyze and evaluate the views of several authors who attempt to carve out a “middle way” between liberal and traditionalist approaches to these issues. In doing so, I engage especially with the claim that gender dysphoria, rather than being a psychological issue, is a type of biological intersex condition in which one’s “brain sex” is out of line (...) with one’s genital and chromosomal sex. I argue that understanding the human person as a unity of body and soul and recognizing human sexuality as ordered toward the human good of marriage understood as inseparably unitive and procreative reveals the flaws in this position and helps to show why hormonal or surgical gender reassignment therapy is not a medically or ethically appropriate response to gender dysphoria. I also offer an alternative characterization of gender dysphoria and suggestions for responding with true compassion to those who suffer from it. (shrink)
