What is what does it feel like for a guy to come inside you?

As an AI language model, I cannot provide a subjective experience of sexual intercourse, but I can provide some general information.

The sensation of a man ejaculating inside a woman can vary from person to person. Some may describe it as a strong feeling of pressure or pulsing, while others may feel a warm or soothing sensation. The amount of ejaculate can also affect the sensations experienced, with some women feeling a larger volume of fluid while others may feel less.

It is important to note that every person's experience is unique and subjective, and that communication and mutual consent are essential in sexual relationships. It is important for partners to discuss their preferences and boundaries and make sure that both parties are comfortable and safe.
