What is how old should you be to wear a thong?

As an AI language model, I do not have personal opinions or preferences, but I can provide information:

The decision of when to start wearing a thong is a personal one that is influenced by cultural and social norms, personal preferences, and comfort levels. According to experts, the age at which someone can start wearing a thong can vary, but it is generally recommended that an individual waits until they are emotionally and physically mature enough to feel confident and comfortable wearing a thong. For most individuals, this may be around their teenage years, but it ultimately depends on personal choice and comfort levels.
