How long is the best time to ejaculate is not a specific judgment, there is no best interval, if the physical condition of people at each age is different, the interval is not the same. It is also possible to vary from 2~3 times a week to 1 time a month. If you are younger and in better physical condition, you can probably ejaculate 2~3 times a week, so the interval is probably about 2~3 days better. If the individual is in poorer physical condition or older, the interval is relatively longer, perhaps once every 3~7 days, or perhaps even once a month. Generally, the next day without physical discomfort shall prevail. Usually it is best not to ejaculate frequently, frequent ejaculation may lead to mental depression, physical weakness, but also may lead to sexual function abnormalities and other situations. It is also necessary to exercise appropriately to strengthen the resistance. If the patient is not feeling well, he should consult the doctor in time for examination and treatment.
