I got my braces in at 13 and out at 15 I think. The orthodontist girl was ALWAYS doing the "accidental" tit rub on my face and at that age excitement was common even when I didn't have a tit in my face.
Last week at the dentist I had a similar situation where I had to try to think of something else as I was getting a half stalk in the chair. Luckily I didn't get too far gone.
