i got my first ones in my ears when i was 4.
2nd ones at 12 (also in the lugs)
3rd one at 16 (top of lug)

still plenty of room for more, but been happy with my lot for the last 16 yrs so im probably done.

I got my first ear piercing when I was 11. My sister was having hers done for her 10th birthday and I had it done on the spur of the moment. The hole is long gone, getting a job meant the end of earings and mohicans :o( I don’t think 10 is too young for ears as it is a very common piercing. Nose, eyebrow, lip, naval, etc would be a step too far for me though.
