Thank you for working so diligently. And indeed, the ear is a very special source of pleasure. Of course - as some suspect - also quite physically and sensually.
However, that is not what "ear" gasm means at all. You can find the solution in the small video. You can read more about the topic on my website: https://befree-tantra.de/tantra-liebesschule-online/orgasmus-der-frau.
If you want to have fun with the seminar cabaret artist Bernhard Ludiwg, you will find two short films here: https://befree-tantra.de/tantra-liebesschule-online/bernhard-ludwig.
And of course you can immediately check in your life how the "ear" gasm works. Have fun with it!
