There is a fetish I quite like. It’s not terribly common, but it’s also not uncommon as these things go, and it’s called somnophilia. It’s the fetish for either having sex with a sleeping partner, or having someone have sex with you in your sleep.
Now, if you don’t get the appeal, that’s totally okay. Fetishes kinda work that way: if they get you hot, they get you hot, and if they don’t, they’re complete mysteries. Take foot fetishes, for example. I don’t get them. They don’t make any sense to me. I struggle to imagine how someone might be aroused by feet. Like, of all things to get you hot, feet? Why feet?
And that’s okay. I don’t need to understand it to know there are people who are turned on by feet, even if I don’t understand why.
Somnophilia has been dipping in and out of the news lately, because of a rather horrifying case in France concerning a man, Dominique Pelicot, who is on trial for drugging his wife multiple times over a period of years and then recruiting strangers (about fifty or so have been identified and are being prosecuted, if I recall correctly) to rape her.

This isn’t actually about the way whenever someone introduces fetishistic elements of a rape into his crimes, people who enjoy that fetish consensually sigh, roll their eyes, and brace for the onslaught from folks who don’t actually understand that the thing separating rape from sex is consent, though I could write that essay, and maybe eventually I will.
I get the taste for somnophilia. I love the idea of being half asleep, one of those really deep sucking sleeps you just can’t drag yourself from, partly aware that my body is being used for someone else’s pleasure but unable to do anything about it, and waking the next morning with the barest of hazy, fragmented memories of it. Whew! *fans self* I personally find that super-hot.
I also enjoy doing this with a lover who finds it as hot as I do.

Yum.
What I want to talk about today, though, isn’t somnophilia itself, nor even the way pop media conflates the fetish with the rapes that Dominique Pelicot staged, but I want to take a step back and ask: Is it even okay at all? Can we consent to sex in such a way that we cannot revoke that consent?
Sex and Commerce and War, Oh My
Sexual consent, according to a lot of folks in the kink community, is informed, freely given, and exists in the moment. Informed means you know what you’re getting into. Freely given means you’re not being coerced, blackmailed, wheedled, pressured, or forced into it. Exists in the moment means you can always tap out, even if you agreed up front.
A lot of folks are deeply uncomfortable about sex you consent to without a way to back out. That’s why they’ll tell you to have a safeword if you’re playing, say, with rape fantasy, where “no” and “stop” might not mean “no” and “stop.” That’s why they’ll tell you to have a nonverbal signal like a bell if your partner is gagged.
And I get that. It’s okay to be deeply uncomfortable about sex you can’t tap out of.
But, as I believe I’ve blogged about in the past, I personally like agreeing to things that I can’t tap out of. That gets me hot.
And here’s an interesting thing: If you take sex out of the picture, we as a society are quite comfortable indeed with agreeing to things you can’t back out of. Like contracts. Or mortgages. Or military service. Try getting three years into your four-year enlistment and saying “you know what? I changed my mind. I don’t want to do this any more.” Ha ha ha ha ha.
It’s really only with sex when we say “consent isn’t consent if it can’t be revoked.”
But…is that really true?
Unyielding Devotion
Last October, Eunice and I published a book. It’s the fourth novel in our Passionate Pantheon series of far-future, post-scarcity philosophical science fiction theological pornography, and pretty much the entire book is a deep dive into Eunice and I exploring the idea of whether you can give irrevocable consent to sex. (Spoiler: We think the answer is yes.)

It’s an even-numbered book, which means it’s erotic horror (the odd-numbered books in the series are Utopian, the even-numbered books are erotic horror). Here’s an example of what you’ll find:
Two doors in the far wall slid open to admit a tall, muscular man and an equally tall, strong-looking woman. He had bronze skin and brown hair that fell around his shoulders, and looked out at the world through piercing aquamarine eyes with cross-shaped pupils. She had shoulder-length hair of brilliant purple that matched her purple eyes, pale skin, and a warm face that smiled easily. They met in front of the cage. She offered her hand. “Hi! I’m Lanissae. I don’t think we’ve met.”
“Royat.” He shook her hand. “This is only my second party. I came here for the first time last month. I agreed to serve as entertainment at this party, so here I am.”
“Royat.” She inclined her head. “It’s lovely to meet you! This is my fifth time as a cage entertainer. Do you know what to do?”
“I think so. Jakalva explained it to me.”
“Good.” A door in the round cage folded upward. Lanissae stripped, then stepped nude into the cage. Royat undressed somewhat more awkwardly and followed her. A drone flitted down to whisk away their clothes. The cage door folded back down. The woman who had given Jakalva and Kaytin their vials approached the cage, moaning with each step. Her tray now held only four vials, two bright red and two deep turquoise.
“What’s happening?” Kaytin asked Chasoi, who stared at Lanissae and Royat with bright, hungry eyes.
“They’ll each take two Blessings,” Chasoi said. “The first one ensures their bodies will remain physically aroused no matter what happens to them. And the second, well, that’s the magic.”
“The magic? What does that mean?”
“One of them,” Jakalva said, “will become desperately horny beyond all reason. Are you familiar with the Blessing of Fire?”
“Yes,” Kaytin said.
“It’s like that, but more violent. It removes inhibition and obliterates self-control. The other does just the opposite, causing intense aversion, repulsion even, to the idea of sex. The cage makes sure neither of them can escape.”
“Oh.” Kaytin blinked. “So whoever gets the first vial will…”
“Yes. But that’s only half of it.”
“Half of it how?”
“That’s the beauty,” Chasoi breathed. “The moment either of them has an orgasm, they switch. Whoever was needy becomes averse. Whoever was averse becomes wild beyond control. They stay in the cage until they collapse from exhaustion.” Her eyes glittered.
I…would volunteer to be cage entertainment. I bet the number of people who would willingly do this is very small indeed, but I would absolutely do it.
Why?
The character Lanissae, who who has signed up to be cage entertainment many times, explains:
“Okay, let me try to explain,” Lanissae said. “It’s…” She paused, regarding Kaytin through hooded eyes. “I like…I like the tiny spaces. I like that little moment of clarity that happens when you switch, you see? There’s that one second when you know what’s going to happen. You see it in their eyes. You know that when that second is over, they will want you so badly that nothing you can do will stop them.” She shivered, eyes half-closed, and slipped one hand inside the plunging neckline of her shimmering, lacy dress. “Mmm. To be seen with such desire, to know that when the moment passes you will not want it and would do anything to make it stop, to know that it will happen anyway…there’s a delicious inevitability to it.” She cupped her breast. Her eyelids fluttered. “It’s such an exquisite surrender. You exist only to be ravished.” She exhaled in a soft moan. “You can’t get away. You lose yourself in how much you don’t want it, but it doesn’t matter. You stand on the brink and for one instant, you see it all so clearly, and you know what’s about to happen, and you also know that you chose to be here. You walked into the cage yourself, of your own free will…oh!” She leaned back on the couch and caressed her nipple beneath her thin dress.
Kaytin stared at her, desire and revulsion roiling within her. “And then,” Lanissae went on, “the violation is over, and the change happens, and you have that moment of clarity again. You feel the heat in your body. For that one delicious second, you know. When the heat reaches your head, the need will take you, and nothing in the world will matter except the person you are about to ravish. Everything stops. You balance on that edge. You recognize each other. You see the humanity there. In that instant, you share a connection that’s absolutely magical. For that one brief second, you see each other, really see each other—not as predator and prey, but as two people sharing an experience. You know that when the moment passes, you will not be able to stop yourself any more than you could stop what was coming when you were the object. You can feel your mind going…mmm.” She caressed her neck with her fingertips. “You embrace that moment of humanity, before it all slips away. It’s…uh! It’s so magnificent to stand on that cliff and feel yourself about to fall.” Lanissae arched languidly, running both hands down her arms. “When I’m in the cage, I live for those moments of connection between the moments of madness.”
Now, I don’t believe that you should explore irrevocable consent in your relationships, of course. If you find that idea repulsive, I 100% get that.
What I argue is that, in the spirit of agency and bodily autonomy, you have the right to explore irrevocable consent in your sexual relationships if you want to. And I have the right to do so as well.
I believe that, if I choose, I can tell a partner “I consent to you doing X to me, and I also consent to being placed in a situation where I can’t change my mind.” I don’t think I have to, or should, but I think I can if I choose to.
My body, my rules. If I want to give a lover permission to use me in my sleep, I have the right to do that.
You may or may not agree (and if you don’t, I’d love to hear your arguments in the comments). I do, though, find it interesting that society enshrines this right to irrevocable consent in basically every aspect of commercial and social life, except sex.
Isn’t that interesting? Sex, something whose connection to consent we’ve long been shockingly indifferent about, now gets an exception carved for irrevocable consent.
I think, honestly, this is at least in part a sign of the intrinsic distrust and fear our society has about sex.
