I got my ears pierced 8 months ago. I never took out the temporary studs
Why didn't you remove the temporary studs?
I want my girlfriend to feel uncomfortable and jealous
It is best to change the temp studs with real earrings. You can end up having an infection for not changing it.
I don't care about the infection I'm going for the effect.
Please consider removing the studs as the only effect you'll have is being sent to the hospital in pain. Find other ways to form an impression of others that doesn't involve hurting yourself recklessly.
