Ummm...a few times in my life I've tried to lick myself - usually when wondering what cats see in it - and I just don't like how my skin tastes.
Therapists saying things like this are what give rise to negative popular stereotypes about the profession. Personally I think she's going too fast. Telling clients to lick themselves should at least wait till the fifth session.
Seriously, does this have anything to do with what you're in therapy for?
