Is it normal to stick your tongue in your....

After you go to the dentist to have a tooth pulled (when you're like 14 and under) cause of baby teeth or whatever other issue you may have...and all the way from the dentist's office, car ride home...after dinner...to like 3-7 days later, you'll be all like "Omg...there's a fresh new hole in my mouth" and rub your tongue against it..like, gentle at first..very cautious and almost mezmerized by it's new-ness and sometimes, maybe a couple weeks later, you'll just take a drink of something or just boredom and you'll slide your tongue across it, it's so trippy and smooth, it's awesome, am I insane or have other people actually done this weird shit? LOL!! XD
