I have 2 holes in each ear, had them for over 30 years, both in the lower part of the lobe, although I haven't worn earrings in the upper holes for yonks!
One of the therapists where I go for my eyebrow waxing has a piercing in that bit of your ear that sort of comes out from your face (oh hell, that sounds completely daft, no doubt there is a proper name for it, it's sort of gristly oh, you know what I mean!) and she has a small aquamarine stud in it, it looks lovely. Some years ago I did think about getting one done myself, but she did say that it hurt quite a bit when she had it done, so somehow I never got round to it!
