Did nipple sensitivity/reactivity increase or decrease for you after piercing?  If it decreased, did it rebound after removal of the piercings?  I really want to elevate my already sensitive nipples so I get goosebumps when they're licked or caressed.

London, I would love to go do a doubles piercing session with you!  I probably can't until early March though.  I will have an extended family beach vacation in late February and want to avoid the questions about my new nipple piercings if possible!!  Let us both ponder about it and do some research, but it could be a really neat experience for both of us!
