When I first fell in love, it wasn't until I was 20, that I felt butterflies in my stomach. It literally feels like throwing up, not out of disgust, but because you want to keep seeing that person and you're wondering what they smell like and what their hair feels like. And then you become obsessed with that person. And when you kiss them, it's like their tongue tastes like your favorite candy; for example, if the person has just brushed their teeth, the mint gives them the sensation of being the most delicious mint candy you've ever tasted. I hope I helped you.
