How is kissing someone with a vertical labret piercing?

I'm heavily considering getting a vertical labret piercing, but one of my biggest concerns is how kissing and oral will be affected. Can people who have this piercing or have kissed someone with it tell me about your experience? Does it get in the way? How noticeable is it? Cold? Does it catch? Be specific!

PS: I'm talking about heavy making out not just pecks on the lips.
