Why Do We Kiss?

We kiss to show we care about each other and want to feel close.

When two people kiss, they use their lips to touch each other’s lips, like giving a soft, warm hug with the mouth. This helps them feel happy and connected, just like when you give your friend a high-five or a big hug after a long day.

Kissing is also like sharing something special, kind of like passing around a cookie in class. When you kiss someone, it's like saying, “I really like you right now,” and that makes both people feel good inside.

Your mouth has taste buds and touch sensors, which help you feel things. When you kiss, your brain gets excited because of the touch and the smell or taste of the other person, it’s like getting a little surprise every time. That’s why kissing feels so nice and can even make people laugh or smile.

Sometimes, people also use kissing to say “I love you” or “I’m happy to see you,” just like how you might say “I love you” when you give your mom a hug before going to bed.
