Premature ejaculation can be classified as primary or secondary. Primary premature ejaculation is characterized by onset at the first sexual intercourse and this state can persist with rapid ejaculation (before or within 1-2 min after entering the vagina); secondary premature ejaculation is characterized by gradual or sudden onset and normal ejaculation before onset, which is not as severe as primary premature ejaculation. The definition of premature ejaculation includes 3 basic elements 1. time to ejaculation evaluated based on a questionnaire; 2. sense of self-control; 3. distress, ejaculatory dysfunction. From the diagnosis of premature ejaculation we should pay attention to the multidimensional factors incorporated, as patients, we should not always focus on time. Many patients, although the time difference may be very small, not only themselves but both sides experience pleasure during sex, at this time patients may feel that they do not get as long as others on time will conclude that they are not normal, so they seek medical advice everywhere and get to the end In the end, they are physically and mentally exhausted. Many times doctors are not in a hurry to give a diagnosis and may not explain it carefully. Patients should be sympathetic to their doctors, and they can compare the three elements mentioned above to see if they are considered premature ejaculation or not. With the introduction of new medications, many patients have experienced significant improvement in their premature ejaculation symptoms. There are many patients who at this time will focus on time alone as a criterion for self-evaluation of efficacy, while ignoring other factors. The sense of ejaculatory control, the improvement of psychosomatic symptoms, perhaps the improvement of the latter two symptoms of patients is more obvious but ignored, so continue to take drugs, and to a certain extent it is difficult to improve. In fact perhaps the therapeutic effect has been achieved before is the previous multidimensional factors. Maybe the patient friends see feel difficult to understand, in fact the ideal sex life is simply to make yourself and your sexual partner feel physically and mentally comfortable on the line, this is what is important.
