3. Pay attention to controlling saliva. Don't keep your mouth wet when you kiss! Please swallow saliva carefully from time to time. If the lips are too wet, pause, control, and then continue. 4. Lock each other's lips. If all goes well, try to "lock" each other's lips and let them "close" together, which will make the kiss more intimate and passionate, and it is also a good start for French kissing. First of all, it's a good idea to put the other person's lower lip between your lips. Some people's lower lip is very wide and can be gently fixed with their lips. 5, ensure breathing. When kissing, you should be able to breathe gently through your nose. If you think your present posture is making it difficult for you to breathe, stop for a while and then continue kissing. In fact, you don't need to be nervous because you can't breathe. Shortness of breath means that you are nervous or excited, which may make the other person feel very happy.
