Thanks for the query.
An ejaculation earlier than one to 1.5 minutes from the time of intercourse is called premature ejaculation which needs treatment. If you fall in this category, then you may need to see a doctor for a complete examination and rule out causes like anxiety, fear, smoking, excessive alcohol, drug abuse, side effect of medications like antihypertensive, antidepressants, etc, diabetes, circulatory disturbances, etc.
Hope this helped.
