Im with you on this one Anniekon I cant stand any part of my ears being touched, although I do enjoy doing it to my partner and I know he certainly likes it :-)
I agree with londondave, one thing to watch out for is moving your tongue directly over the persons ear hole! That will undo all of your hard work for the past three weeks!!!
I like just under my ears being gently tickled and the lobe massaged and light strokes down the cartelidge and delicate nibbles and then kisses down my neck.....ooooh....
