For As Long As I Can Remember I've Been Able

For as long as I can remember I've been able to pop the frenulum of my lower lip by pulling on it. It feels the same as poping my fingers toes or neck. But I've never met anyone else who could do it? I've also googled if it was possible and I've found no answers? Is something wrong with me? It doesn't hurt at all but could it cause long-term damage to my lip or mouth?
