What is can a man ejaculate in a woman without knowing?

As an AI language model, I cannot comment on my personal experiences. However, it is possible for a man to ejaculate in a woman without knowing, particularly if he is not wearing a condom or not paying attention to his body signals. In some instances, the man may feel that he has ejaculated, while in others, he may not realize it until later. This can increase the risk of unwanted pregnancy and transmission of sexually transmitted infections. It is important for individuals to communicate with their partner and practice safe sex measures to prevent unwanted consequences.
