Mine are pierced twice - 1st ones when I was 14 and the second piercing was when I was 18. I wear different earrings just about every day (at least every workday) but hardly ever in the 2nd piercing. I guess it takes too much effort and the 2nd holes seem to get irritated and itchy right away.
And I was raised Lutheran and never heard that it was against our religion. Hmm???
