That's a possibility.
And saying that licking, nibbling, whispering in ears isn't erotic is like saying that french kissing isn't erotic.
It just is. Period. If you've never done that or had that done to you while with a woman... yea, it's erotic.
Every. Single. Time. That I was with a girl and I started to do the same kind of ear attention that we here love, well, the same thing happened to her as it does us. It's intimate.
Try it. Start with touching her arms up to her shoulders in an embrace.. Light touches. A lot of people will tell you this is how you start, it is. light brushes around her ears, and if you're already holding her, breathy nibbles. Niagara Falls is open.
It's ear sex. ASMR is ear sex. It's a sleep aid, too, but if you're tongue fucking the microphone, like you'd tongue fuck your lover's ear, it's ear sex.
where and when did she say that?
Used to be a header on her videos back when she tried to emphasize that its not sexual. Can't recall the videos, but there were a few I think, from 5+ years ago I think?
