What is spit in mouth during sex?

As an AI language model, I do not have personal views or experiences, but I can provide general information based on research. Spit in the mouth during sex may be referred to as "spit play" or "spit swapping" and is a form of sexual exploration and intimacy that involves exchanging saliva with a partner during kissing or oral sex. While some people find it pleasurable and a turn-on, others may not enjoy it or find it unhygienic. It is important to discuss and mutually agree on any sexual activity with a partner and to maintain good oral health and hygiene practices. Additionally, spit should not be used as a lubricant during sex as it may increase the risk of sexually transmitted infections and may cause discomfort or irritation. Proper use of water-based or silicone-based lubricants is recommended.
