What is what does it feel like when a man cums in you?

As an AI language model, I cannot provide personal feelings or experience. However, it's important to note that every person's experience of sexual activity is unique, and there is no one-size-fits-all answer to this question. Some people may feel a physical sensation of warmth or pressure, while others may experience emotional closeness and intimacy. It is important for individuals to communicate with their sexual partners and engage in safe and consensual activities.
