Hi! gyanendra.timsina, welcome to HealthcareMagic forum, gyanendra ,by quick release of sperms ,i guess you mean Premature ejaculation(PME). PME is usually due to psychological reasons .At times stress,depression,financial problems,unrealistic expectation about performance ,lack of confidence,fear ,guilt,general health,over sensitive glans penis etc can contribute to it.Treatment requires lot of communication between the patient and the doctor. A combination of exercises and medicines can help in this .A proper counselling with the doctor would help further.Exercises like START AND STOP TECHNIQUE can help in which once you have reached a state of arousal ,your partner should stop stimulation and allow a little of relaxation . Another technique is called KEGELS EXERCISE in which one has to squeeze the penis shaft to stop one from ejaculation and the gradually release it. This gives you more control over ejaculation. At times a simple local anesthetic gel applied over penis might help in PME.This reduces the over-sensitivity of the penis . Medicines like selective serotonin reuptake inhibitors are prescribed by doctors after proper consultation with the patient also helps a lot. so a combination of behavioral therapy,exercises & tablets would help resolving your problem.Consult a urologist or dermatologist dealing with sexual problems for best results. regards, Dr.chawda
