There is no fixed standard answer to how long a man’s sex life is considered normal, it varies from person to person, from environment to environment, and varies from person to person due to sexual habits, developmental status, physical quality and age. There are statistics that show a more satisfactory sex life time is generally about 8 minutes on average, 3-15 minutes should be normal. No sex for a long time, when the sexual stimulation is relatively strong, sex time is bound to shorten, occasionally a few short sex time is also normal. If you have a regular sex life, but still have a short sex life, such as more than three months, should promptly go to the regular public hospital urology or male department for consultation and treatment. Of course, sex is not just a matter of time, it is the exchange of emotions between the two sides, as long as both sides are satisfied, even if the time is less than 3 minutes is normal.
