Hi, Welcome to health care magic, This is a very common problem and unfortunately, there’s no particular medication for the same. The commonest cause of premature ejaculation is the anxiety of performance or lack of sexual experience or increased excitation during forplay. A behavioural technique such as squeeze-pause technique, desensitizing creams, distraction techniques, SRRI (selective serotonin reuptake inhibitors) are few common treatments useful in premature ejaculation. You should take consultation with a sex therapist or psychologist, to be assessed properly. Regards.
