Thank you for asking. It strongly appears to be a problem of premature ejaculation. Anxiety is a n important factor known to be associated with it. It is also known to be a contributing factor for PME. the management of it depends upon managing the causative factors. Management of stress and anxiety are the key goals. Regular exercise, healthy lifestyle, adequate sleep, are important. It is not a serious problem. It is very common and completely curable. Masturbation and porn use are known to cause erectile dysfunction and therefore should be managed.
