Is it normal balance?

Is it normal to balance things on my tongue CONSTANTLY? It's not a sexual thing but I just really like the challenge of trying to balance something perfectly on my tongue. I'll spend hours lying on my back with my tongue sticking straight up trying to balance something on it. I use small things like pencils, pill bottles, books, etc. but I also sometimes do it with larger things like trash cans, recycling bins, lava lamps, and even my friends sometimes! Of course, my tongue isn't always strong enough to support the weight but I'm still not satisfied until I've at least tried. Anybody else do this, too?
