Sometimes kissing allows you to understand the depth and length of the other person

In the movie Pretty Woman, Julia Roberts plays a prostitute who never kisses her clients because her mother told her that kissing is an intimate act but sex is not. And surveys show that sex workers do avoid kissing clients to prevent becoming emotionally involved with them.

1. Before and after the lips touch, the lovers will usually look at each other lovingly for a moment at a very short distance.

If one of them feels uncomfortable with their relationship, he or she will not be able to gaze at the other person naturally and will involuntarily look away or interrupt the other person's gaze. This makes kissing a way to test the feelings of both parties.

2. Kissing between lovers is an act without gender distinction.

When kissing, both parties feel the same body organ "entering" and "being entered" at the same time. Moreover, the skin of the lips is the thinnest in the whole body, and its surface is covered with nerve endings and has rich sensitivity.

3. Kissing won’t get you pregnant – so it’s done purely for pleasure.

(Be careful when someone says, just give it a kiss, you won’t get pregnant anyway…)

4. The series of small movements of two people when kissing is actually an unconscious dialogue——

Who has more aggressive oral movements, who opens their mouth reluctantly, and who just keeps their mouth open without moving - all of this says a lot about how they feel about the relationship.

5. People generally only get to know other people through four senses - vision, hearing, touch and smell.

During kissing, not only is the rarely used sense of taste greatly stimulated, but the smell emitted by the other person is also stronger than usual. By tasting the other person's unique flavor and smell that is different from others, the impression of this person will be deeply engraved in your mind.
