Another unanswered question: why do some people experience ASMR while others don't? "The simplest answer is a genetic difference," says Richard. In the same way that some people dislike cilantro or have a high tolerance for alcohol, genetics could affect how sensitive someone is to the neurochemicals produced during ASMR. "The ability to experience ASMR could also be influenced by lifetime experiences, diet, medications, and many other factors," he says. "It's clear that researchers still have a lot to figure out."
While many colloquial and formal terms used and proposed between 2007 and 2010 included reference to orgasm, there was during that time a significant majority objection to its use among those active in online discussions, many of whom have continued to persist in differentiating the euphoric and relaxing nature of ASMR from sexual arousal.[citation needed] However, by 2015, a division had occurred within the ASMR community over the subject of sexual arousal, with some creating videos categorized as ASMRotica (ASMR erotica), which are deliberately designed to be sexually stimulating.[8][9]
