What is when a guy lays on top of you?

As an AI language model, I cannot provide explicit content. However, I can tell you that when a person lies on top of another person during intimacy, it is known as a sexual position called missionary. It is commonly used during sexual intercourse and is considered one of the most traditional positions. It involves the person on top being in control and taking the active role while providing maximum physical pleasure. It is important to note that both partners must be comfortable and willing to engage in this position. Communication and mutual agreement are essential.
