I research sexual perversions and paraphilas – here’s what we’ve learned about them

After allegedly sending messages detailing cannibalistic fetishes, Hollywood actor Armie Hammer hopes to relaunch his career with a new podcast and movie.

Following the 2021 social media cannibal scandal, Hammer was also accused of rape and abuse by various women, but consistently denied any criminal behaviour and was not charged.

Now, it seems, Hammer is laughing off the cannibalism allegations. Speaking to his first podcast guest, Tom Arnold, Hammer says, “I’m not gonna lie. I’m just like, Hey, I’m a cannibal!”

But being sexually aroused by the fantasy – or reality – of cannibalism is real. I should know, as it’s one of the subjects I discuss in my latest book Sexual Perversions and Paraphilias: An A-Z

Paraphilias are uncommon types of sexual expression often described as sexual deviations, sexual perversions or disorders of sexual preference.

They are typically accompanied by intense sexual arousal to unconventional or non-sexual stimuli such as enemas (klismaphilia), statues (agalmatophilia), teeth (odontophilia) and vomit (emetophilia).

To many people paraphilias may seem bizarre or socially unacceptable, representing the extreme end of the sexual continuum – and in some cases, such as zoophilia (having sex with animals) and necrophilia (having sex with dead people), may be illegal.

Paraphilias may be laughed off, dismissed or leave some people disgusted, but there’s a pressing need for more research into uncommon sexual behaviour given how little we know.

Sexual fantasies and behaviour are a fundamental part of the human experience. What is considered immoral or even illegal changes according to the social and temporal context. But whatever sexual desires are considered illicit or depraved in a particular time and place are also stigmatised.

Researching paraphilias, even the most distasteful or criminal, is essential to help safeguard vulnerable groups. Research can also help minimise the discrimination faced by those with uncommon sexual interests, helping ensure their access to sexual health care and psychological support, which can be lacking.

Vorarephilia

Vorarephilia – or “vore” – refers to being sexually aroused by the idea of being eaten, eating another person or observing this process for sexual gratification.

Most of the fantasies of vorarephiliacs involve being the ones eaten. Devouring someone could be viewed as the ultimate act of dominance by a predator and the ultimate act of submission by the prey.

The most infamous vorarephiliac is arguably Armin Meiwes from Germany.

Meiwes had allegedly been fantasising about cannibalism since his childhood and frequented cannibal fetish websites. He posted around 60 online adverts asking if anyone would like to be eaten by him.

In March 2002, Bernd Jürgen Brandes responded to Meiwes. They met up only once. Meiwes bit off Brandes’ penis, which the two of them cooked and ate.

Brandes was videotaped being stabbed to death by Meiwes in his bath. The body was then stored for Meiwes to eat.

Meiwes was eventually convicted of murder and imprisoned for life. However, it’s worth nothing that although some paraphilias are illegal, most cause no psychological or behavioural problems when they are engaged by consenting adults.

Dacryphilia

Dacryphilia is getting sexual arousal from seeing someone cry.

I have published a number of studies on dacryphilia. One involved interviews with eight dacryphiles: six women and two men, from the US, UK, Romania and Belgium.

It showed there were sub-types of dacryphilia, even among such a small group. Based on the interviews, I identified three types of dacryphile.

Compassionate dacryphiles are sexually aroused by the compassion of comforting a crier.

Dominant or submissive dacryphiles are sexually aroused by either causing tears in a consenting submissive partner or by being made to cry by a consenting dominant partner.

“Curled lip” dacryphiles are sexually aroused by the curling of a protruded bottom lip during crying.

Eproctophilia

Eproctophilia involves being sexually aroused by flatulence.

In 2013, I published the first case study of an eproctophile. The case concerned a 22-year-old single man, Brad*, an American from Illinois.

Brad recalled that in middle school he had a crush on a girl who had farted in the class. Brad said:

This blew my mind [I] knew by simple biology that girls farted, but hearing that the girl I had been fawning over was capable of such a thing sparked a strange interest in me.

Brad first engaged in an eproctophilic act with a male friend in his mid-teens. Up to that point he had considered himself heterosexual. However, this changed when he heard his male friend fart.

Brad said it was “appealing in sound” and that he began fixating on it. He set up a bet with the wager being the right to fart in the loser’s face for a week. He continued to lose such bets once every few weeks for about two years.

Apotemnophilia

Apotemnophilia refers to being sexually aroused by the fantasy or reality of being an amputee.

Some apotemnophiles may pretend to be amputees but, for a minority, the behaviour involves obsessive scheming to convince a surgeon to perform a medically unnecessary amputation.

To most people, this might seem like a type of masochism, but case studies suggest that there is no erotisation of pain – only of the healed amputated stump.

Salirophilia

Salirophilia is sexual arousal from soiling or dishevelling someone attractive, which can include tearing or damaging the desired person’s clothing, covering them in mud or filth or messing up their hair or make-up.

My 2019 case study involved Jeff*, a 58-year-old Australian heterosexual. Jeff recounted that when he was young he wanted to masturbate in strange places such as lying under a cabinet in a dirty garage.

Jeff said that he engaged in solitary salirophilic practices regularly but very infrequently with female partners because it was difficult to find like-minded women.

He was also a fan of the television show Fear Factor in which contestants perform revolting tasks for prize money, such as eating rotting food or being submerged in foul fluids. These were a source of sexual arousal for Jeff. He told me: “I just find the defilement of an attractive woman’s body erotic.”
