For the record, this is based after something that happened to me when my teacher accidentally put her hand in a far more intimate place. (Woops!) When it happened, I instantly started laughing while upside down. I’m great friends with my instructor so it was chalked up to be nothing more than a funny incident between girlfriends.
Of course, every student is different, and I suggest you should say something to your teacher if you don’t wish to be held/touched in any certain way beforehand. 😉 Safety and comfort first.
