Since I have never had the experience let me ask.....
Does it feel different (better or worse) receiving a BJ when the provider's tongue is pierced ?
And who is worth a visit for this experience ?

I never noticed a difference.

Only one provider made it uncomfortable. Maybe because she used too much pressure or because it was too big. Otherwise, I didn't notice any great difference. A provider having a pierced tongue doesn't make it or break it for me.

Hey you guys. You should give Jada a call and ask her to bring her special toy. She has a mini vibrator tongue piece that she can wear while doing your thing.All I can say is FU__ING  WOW!!!!

I've only had a limited number of experiences with tongue rings.  Now of course as always, technique as well as the size and/or kind of ring surely can make a difference I'm sure, but for me I was not really able to tell anything different or special at all to be honest.  However, this vibrating tongue piece thing woody is talking about might be a completely different story!!

The mini-vibrator makes a big difference.
