ASMR sex fetish explained as Sydney Sweeney's graphic scene in Euphoria episode could trigger 'brain orgasm'

Experts have explained the ASMR-related fetish featured in the latest episode of Euphoria, revealing how it could trigger a so-called 'brain orgasm'.

The latest series of the hit HBO show has certainly been divisive, with some viewers claiming a number of scenes have 'gone too far'.

Sydney Sweeney's character, Cassie, has entered the world of OnlyFans, leading to some unexpected NSFW moments. From 'sploshing' to 'puppy play' - we thought we'd seen it all.

But no, enter episode five... titled This Little Piggy.

In one particular scene in the latest instalment of Euphoria, Cassie can be seen rubbing her breasts on a microphone and saying: "Do you like the sound of that?"

She then asks: "Do you want to hear my p***y?" Before putting the microphone down below and moving it around.

The scene is an example of an ASMR sex fetish that's apparently getting ever popular in the bedroom.

What is ASMR?

Autonomous Sensory Meridian Response, more commonly known as ASMR, went viral a number of years ago now and often involved food.

However, it has since made its way into the bedroom, which makes sense given how relaxed it can make you feel.

And it's certainly popular according to Exploding Topics, in January 2026, 'asmr' was the most searched for keyword on YouTube, with 38 million monthly searches.

Dr Shirin Lakhani, from Elite Aesthetics, told Cosmopolitan: "Sexual ASMR is the erotic use of specific visual and auditory triggers to enhance sexual experience. For some people this may be that a sound such as whispering triggers what is often known as a 'brain orgasm'."

Meanwhile, psychotherapist Charlotte Fox Weber added: "Sexually, it’s a kind of personal attention that shows close attunement. It’s flirting with intimacy.

"Sex is about so much more than intercourse. It’s about pleasure, sensation, feelings, fantasies, playing. ASMR creates a zone of excitement and titillation."

Dr Lakhani went on to explain that it's key to try out a number of different types of sexual ASMR to really decide whether its something you want to implement between the sheets.

"The key to using it to enhance your sex life is to find a trigger sound that works for you," the sex and relationships expert continued.

"These can be any number of things from the sound of your partner whispering, to the sound of a shower running, to a scratching noise to blowing, and so on. The list really is endless and very much down to personal preference."

Dr Lakhani added: "Sexual ASMR can help you to relax and to reduce anxiety in the bedroom. The benefit is that once people find a type that works for them they can incorporate it into their sex life to make it more exhilarating and fulfilling."
