I just went through all the videos on this page, and it seems I only respond to female voices. The other videos of scratching and stuff, didn’t do anything for me. Now that I think about it, I don’t get ticklish if I sit next to another guy. Even the music I listen to tend to be all female vocalists. I’m not a sexist, but I guess being a guy, I respond to higher-pitched female voices. At night, I hit the Japanese radio stations on my phone looking for female DJs and if I catch one talking, I close my eyes, and I’m sleeping before I can count to 20.
ASMR is usually precipitated by stimuli referred to as 'triggers'. ASMR triggers, which are most commonly auditory and visual, may be encountered through the interpersonal interactions of daily life. Additionally, ASMR is often triggered by exposure to specific audio and video. Such media may be specially made with the specific purpose of triggering ASMR or originally created for other purposes and later discovered to be effective as a trigger of the experience.
