ASMR was a pretty niche content until it turned mainstream. Ear licking, lens kissing, whispering, and JOI(Jerk-off instruction) are pretty mainstream sexual ASMR contents, on the other hand; barber shop, page-turning, scratching etc on the non-sexual spectrum. It's pretty popular now and is present on all major video sites: YT, Twitch, Kick, etc. ASMR content is mostly used as a sleeping aid. Anyone with a good mic and a decent knowledge of audio editing software can make a good ASMR.
Half of those "ASMR ARTISTS" are pure ear rape
