I recently had someone whisper ASMR to me in a sexual situation, and I’m curious if someone could explain what its appeal is (sexual or otherwise) and anything that someone unfamiliar with it would benefit from knowing. Should I assume it’s something he’s interested in if he made a point of doing it? How does one get into ASMR from not knowing much about it? Links or examples welcome. Thank you.
