Premature ejaculation or Ejaculation is a fairly common phenomenon that affects every tenth man. The fact is that there is no absolute rule for how long a man should last, and the average time (based on a sample of 500 couples) is five and a half minutes. If it occurs after two minutes on average, you may consider it a problem. This can be psychological in nature, but later in life it can also be physical (high blood pressure and cholesterol, diabetes, testosterone levels, etc.). Fortunately, there are natural methods and techniques that can increase stamina, but remember that premature ejaculation is only a problem if it bothers you and your partner. If you're happy with your sex life, don't dwell on it.
