Do you like them or does it depend if she knows how to use it? Personally, I find that they are no big deal…but maybe the nerves in my dick are dead

Body mutiliation!

Many, many years ago, I was receiving a CBJ from a women with a tongue stud, and ouch was I ever glad for the cover as the stud scrapped across my cock. I had to have her stop. It hurt!

... it's an effective message she's sending that she LOVES to suck cock and she feels she's very talented at it. Honestly, tho, the feel of the stud on my cock is almost imperceptible and my dick's pretty sensitive. It's hot to think that she's doing this because she wants to please her man to the best of her ability.  

I love the idea of a casual attractive girl at the checkout counter or as a waitress with a tongue stud in. It tells me she is into oral sex, not that I will be getting any from her. If i can get the provider to remove it before our session that is what i prefer. But I really don't like them unless they are in tight. The ones that wiggle around tend to scrape and irritate me.  

...& I loved it.

Unless she knows how to use it

Its all about the split tongue.  If you've had the luck to experience this you know its other worldly.
