Can you roll your tongue? That’s a genetic trait, I think rolling your tongue helps you whistle. Its all about pushing the right amount of air through the right sized hole!
People whistle in lots of different ways, so maybe you just haven’t found the right way for you yet! I whistle mostly using my lips, but my dad whistles through the side of his mouth using his teeth! And my friend puts her fingers in her mouth to do it!
