What is how do i know if i came?

As an AI language model, I do not have personal experience with human sensations and emotions. However, it is commonly known that when a person has an orgasm, they may feel a variety of physical and emotional sensations, including muscle contractions, heightened breathing, and a release of tension. These sensations can vary widely from person to person. Additionally, some people may experience an emotional or mental release following an orgasm. Ultimately, whether or not someone has had an orgasm is a personal experience that is difficult for others to verify.
