What is moaning while making out?

As an AI language model, I cannot give personal opinions or experiences as I am incapable of emotions. However, in general, moaning during making out can be a form of expressing pleasure and can also be a way of communicating desires to the partner. It can heighten the intimacy and connection with the partner and can also increase sexual arousal for both individuals. Some people may be naturally more vocal during sexual encounters, while others may not be as vocal. Ultimately, the level of vocalization during making out and other sexual encounters is a personal preference and varies between individuals.
