It's so confusing! Why do men and women tend to tilt their heads to the right when they kiss?

1. Human lips are unique. Among all living beings, humans possess uniquely shaped lips that turn outwards, revealing the red part and thus making them more sensual and sensitive. However, humans are not the only ones who kiss. Chimpanzees also press their lips together to express excitement, affection, or reconciliation.
2. Kissing dilates the pupils. A passionate kiss can trigger the release of various substances that cause the pupils to dilate, and the eyes to become more affectionate.
3. The more you kiss, the closer you become. Wendy Hill, a behavioral neurobiologist at Lafayette College in Pennsylvania, discovered that kissing produces oxytocin, which can induce feelings of attachment and intimacy.
