But so many fans associate sexual and ASMR pleasure that an entire subgenre of ASMR erotica (or ASMRotica) has evolved. They prefer to think of it as a kind of “sound massage” – less about sex and more about relaxation. Some ASMR enthusiasts object to the idea of conflating it with sexual arousal. In some cases, it can also increase in intensity as it spreads into the limbs and lower back. In fact, it feels so good that people have referred to it in terms as extreme as a “brain orgasm.” The sensation generally moves down from the head into the spine and shoulders. The term ASMR is an acronym for “autonomous sensory meridian response.” But that’s less important than the fact that – for many people – it just feels good.
