Hello.. Seems like a case of premature ejauculation.. Do not worry it is curable... I suggest you to have healthy diet, and maintain good hygienie and healthy lifestyle.. You do exercises daily.. Self motivational therapy is the best...apart from that medications can also be given depending on the requirement... Consult a physician

There may be some anxiety issues..having spicy food, excessive tea, coffee or any kimd of addiction. The person needs some.counselling and supportive medications..
