The amount of time a man waits before ejaculating is very different for each person and depends on their interests and the situation. There is no set "normal" amount of time between sex for men to ejaculate, but most do it within a few minutes.
Some men may come quickly because they are highly aroused, while others may last longer because of things like training, control methods, or their own bodies. Some people and their partners may be worried about premature ejaculation, which is described as regularly ejaculating within one minute of insertion. But it's important to remember that sexual happiness and closeness aren't just based on how long you're making love. Talking to your partner about your needs and wants is key to a satisfying sexual relationship.
