Time which you mentioned, if correct, does not label you under definition of premature ejaculation. Most importantly you require treatment if it is causing you severe distress or martial disharmony.

Treatment may not be needed. Practicing relaxation techniques or using distraction methods may help you delay ejaculation. For some men, stopping or cutting down on the use of alcohol, tobacco, or illegal drugs may improve how well they can control ejaculation...if no improvements medical treatment needed..consult nearest psychiatrist they will do the needful.
