Thank you for asking. It appears to be a problem of premature ejaculation. Stress and anxiety are two major risk factors for it. Most of the cases, there may not be any specific cause to it. Lack of physical excercise, irregular sleep patterns, etc are important sources of stressor. The management would consist of promoting relaxation of body and mind at the time of sex. With the help of suitable medication and changes in routine this can be treated.
