Sex Terms You’ve Never Heard: From CBT to CEI & Beyond

This post is based on a Sex With Dr. Jess podcast episode featuring Sunny Megatron. Scroll down to listen or listen on Spotify or Apple Podcasts.

What Counts as a “Normal” Fantasy?

What turns someone on might surprise others—but that doesn’t make it wrong. In a world where sexual fantasies are often hidden behind closed doors and filtered out of mainstream studies, a growing vocabulary of kink and fetish acronyms reveals just how varied, creative, and expressive people’s desires can be.

While a study out of Quebec found that fantasies such as swinging, BDSM, and threesomes are common and “normal” (with over half of participants reporting them), the reality is that many desires extend beyond the bounds of academic inquiry.

That’s where lesser-known acronyms come in.

Kink Acronyms 101: From Familiar to Fantastical

Sex educator Sunny Megatron recently joined the Sex With Dr. Jess podcast to decode the sex terms that rarely show up in textbooks. From CEI to ASFR, here are a few that stand out:

CBT: Cock and ball torture

This can include everything from gentle squeezing to bondage, ball stretchers, clamps, and even full-contact ball busting.

CEI: Cum eating instruction

Often paired with JOI (jack off instruction), usually in a dom-sub dynamic, and frequently rooted in taboo play.

SPH: Small penis humiliation

Involves psychological play and consensual embarrassment.

ABF: Adult breastfeeding fetish

Not necessarily about lactation, but more often about the eroticism of care, comfort, and vulnerability.

CFNM: Clothed female, nude male

An inversion of mainstream objectification that centers the clothed partner’s power and gaze.

ASFR: Alt sex robot fetish

Sometimes referred to as technosexuality, especially relevant in a world where Bluetooth-connected toys like the We-Vibe Chorus and We-Vibe Sync 2 blur the lines between tech and touch.

The Psychology of Kink: Power, Play & Permission

Many of these fantasies involve submissive men and dominant women—a dynamic that directly challenges cultural norms of masculinity. Kinks like CEI or CFNM provide a mental reprieve from societal expectations of dominance and emotional suppression.

This kind of exploration is not necessarily about the acts themselves, but about rewriting personal narratives around power, control, and vulnerability. For some, it’s healing. For others, it’s just hot.

And for anyone looking to explore dominant/submissive roles in a playful way, a toy like the We-Vibe Pivot can be an excellent starting point. It’s discreet, app-controlled, and ideal for giving control to a partner, whether across the room or across the world.

Shame, Humiliation & the Erotic

Erotic humiliation is another thread running through many of these kinks. It’s not about degradation but about consensual embarrassment—such as being asked to perform a sexy task in front of others or being lovingly teased.

These types of fantasies often stem from early experiences or internalized cultural messages. For those looking to process shame through pleasure, even seemingly taboo kinks like CBT or CEI can become cathartic and empowering when approached with consent, communication, and curiosity.

Playing With Consent: SSC and RACK

All these acts—no matter how edgy—rely on enthusiastic, informed consent. The frameworks of SSC (Safe, Sane, and Consensual) and RACK (Risk-Aware Consensual Kink) guide participants toward ethical, joyful exploration.

Tools for Pleasure, Play & Power Exchange

For those curious to dive into sensation, dominance, or power exchange dynamics, consider these tools:

We-Vibe Melt: Perfect for surrendering to hands-free clitoral stimulation during JOI scenes.
Magic Wand: Ideal for intense sensation play, especially in spanking or OTK scenes.
We-Vibe Tango X: A powerful bullet vibe for pinpoint pleasure or humiliation play when the submissive is being edged.
