A kiss is not just a simple touching of lips. A new study finds that the quality of a kiss can determine how a relationship develops. At the same time, the study also pointed out that men and women have different attitudes towards kissing, and the feelings they hope to get from it are also different; compared with women, men are more likely to use kissing as a transition to further intimacy, and sometimes to reconcile with their girlfriends.

According to a recent report by Fox News, a University at Albany survey found that 59% of men and 66% of women were originally attracted to someone, but may completely lose interest in him after a kiss. In the study, men tended to French kiss, with their mouths wide open. Researchers analyzed that this may be because men have poorer senses of taste and smell than women and require more saliva to feel and evaluate each other. Women prefer gentle and drizzle-like kisses, preferably from shallow to deep, and gradually get better.

At the same time, men can "get straight to the point" and have a romantic relationship with their lover without having to kiss. For women, sexual relations must not occur without kissing. They regard kissing as an important way to establish and check their relationship. "Kissing helps women identify their lover's loyalty. If the frequency of kissing suddenly decreases, or the way they kiss changes, she can be sensitive to the waning interest of the other person."

Earlier, at the American Sexology Society conference, participating experts found that the average duration of a good kiss is 45 seconds, which can affect 34 muscles in the face, thereby triggering sexual desire. The famous German sex psychologist Dr. Herna Eli pointed out that there are three best ways to kiss, which are simple and practical:

First, closed type. In the initial stage of love, both of them are a little shy. The kiss at this time should be with their mouths closed and limited to lip-to-lip kissing.

Second, half-open and half-closed. Move the upper lip of one party between the upper and lower lips of the other party, and then rub it gently from side to side. This can be extremely exciting for both parties.

Third, concave and convex type. The gentle friction between lips, and then sucking each other. In this way, the contact is more comprehensive and the feelings expressed will be more passionate.
