Human sexuality is a complex and diverse issue. Pornography, homosexuality, sadomasochism, other so-called perversions have real moral implications and affect real people. An issue as intensely personal as sexuality calls for a moral guide just as personal. Thankfully, in moral egoism, we have a theory of morality and ethical behavior centered on the individual. Proposed by philosophers like Ayn Rand, moral egoism in its simplest form states that an action is right for a person if, and only if, it promotes their best interests. As a consequentialist moral theory, egoism posits that the results of an action are what determine the moral worth thereof. Moral egoism also accounts for circumstantial relativism – the idea that the situation surrounding an action helps determine whether that action is right or wrong. If a given act in a given situation produces (or is likely to produce) outcomes that advance a person’s agenda, it is right. If not, it is wrong. Applied to sexual ethics, egoism requires individuals to rationally examine the potential outcomes of a sex act in a given situation to determine if engaging in the act is in their best interests. A sex act, then, is perverted (morally wrong) inasmuch as it opposes a person’s best interests. Through this lens, sexual activities that have traditionally been viewed as morally corrupt – such as promiscuity, sodomy, and masturbation – are actually morally acceptable behaviors.
Promiscuity, for example, is morally acceptable so long as the promiscuous person is honest with their partners that the relationship is purely physical in nature and safe sex methods are used. Sex is a near-universal desire in humans. Thus it is in most people’s best interests to have sex. If a person desires a large quantity of sexual contact, or multiple partners, being promiscuous could be in that person’s best interests. Desire alone does not make promiscuous behavior acceptable, however. As a consequentialist theory, moral egoism is concerned with the results of an action to determine moral rightness. It is for this reason that the would-be Lothario or Jezebel is morally obligated to practice safe sex and honesty about relationship expectations with potential partners. Unsafe sex has the potential for results not in the promiscuous person’s best interests, namely disease and unwanted pregnancy. Dishonesty with partners could create vindictive responses. Obviously, jilting Glenn Close’s character from Fatal Attraction is not in one’s best interests. Sodomy is also morally acceptable between consenting adults who find the act mutually pleasurable and perform the act safely. The egoist sodomite is morally required to use safe sex practices when engaging in anal or oral sex. As with promiscuous behavior, sodomy carries the risk of disease. Contracting a sexually transmitted is in no one’s best interests. Further, consent and mutual pleasure are morally necessary. Non-consensual sodomy carries the obvious legal ramifications of arrest and potential conviction for rape. One would be hard pressed to argue an arrest to be in one’s best interests. Masturbation is morally acceptable for those whose sexual desires cannot be met in full by their partners. Some people desire more sex than they receive from their partners, and it is in their best interests to relieve their sexual needs by themselves in lieu of engaging in rape or soliciting a prostitute.
Some will object to “deviant” sex on religious grounds. They will appeal to divine commands as condemning the immorality of non-missionary, non-heterosexual acts. The Christian Bible, for example, contains many prohibitions against sodomy and masturbation, and any sex outside of marriage is forbidden by church dogma, much less having sex with multiple partners out of wedlock. These dissenters appeal to the divine command theory of morality that states that an action is right if, and only if, God commands us to do it. According to this perspective, because God commands us not to have any sex other than vaginal sex with our spouse, these acts are immoral. Others may claim that engaging in promiscuous acts cheapens sex or fails to honor the other as a person. Deontologists like Immanuel Kant would likely take this perspective. Kant’s first Categorical Imperative states that we should only act on maxims we can will to be universal law. If everyone were to engage in promiscuity, the first Imperative argues, no one would form lasting, non-physical relationships. The second Categorical Imperative proposed by Kant states that we should always treat people as ends unto themselves, never as a means. Followers of CI2, then, object to promiscuity as failing to respect the personhood of the one-night stand. Still others object to sodomy and masturbation as defying natural law. As one of the natural functions of a human being is procreation, any sex act that does not (potentially) result in fertilization of an embryo is immoral.
Unfortunately, the objections of religious zealots appealing to divine command theory are essentially meaningless. As the existence of God cannot be proven, any morality derived from the deity is suspect. The egoist can look to studies, facts, and statistics to help determine what is in his or her best interests sexually. The first Categorical Imperative objection fails to conceive that some people might prefer not to be promiscuous. Egoists may be promiscuous or not, depending upon what best serves their interests at any given time. Kant’s second attempt at outlining a moral code also fails in condemning promiscuity adequately by failing to take into account the will of the seduced. It presumes the seducer is acting upon the seduced with no input from the seduced party. Egoism, on the other hand, only provides moral sanction to promiscuity if both parties are consenting. Appeal to the natural law theory to object to deviant sex relies on the premise that humans have a natural function. However, proving what this innate function is is impossible. There is no “functionometer” to measure how well a human functions and no means to adapt that function to varying situations. Moral egoism, however, takes into account that what’s in one’s best interests can change over time and in relation to differing circumstances.
Religious leaders and intellectuals alike struggle to rationally explain why “deviant” sex acts like promiscuity, sodomy, and masturbation are immoral. The theory of moral egoism provides a rational explanation that justifies these kinds of acts as morally acceptable in certain circumstances for a particular person. A given sexual behavior is therefore immoral only if it hinders a person’s best interests. As such, laws banning acts like sodomy and social stigmas regarding promiscuity and masturbation should be reevaluated. As there is no logical moral objection to the acts and no harm to society by engaging in them, there’s little reason to perpetuate antiquated ideas regarding these common aspects of modern sexuality.
