Dreaming ejaculation at night is normal. When male patients mature in sexual development, there will be sexual excitement, too tired to work during the day, or study is very stressful, the pressure relaxes after sleeping at night, and the penis erection rubs against the underwear at night, and at the same time there is dreaming, especially dreaming related to sex, and then ejaculation will occur. Frequent ejaculation may occur especially in many developing and mature males who do not have reasonable intercourse and masturbation. If ejaculation occurs 3-4 times a month, this is not inappropriate. If there is frequent ejaculation in a short period of time, this needs to be taken care of by not having too much exposure to sexually explicit words and pictures to minimize the occurrence of ejaculation.
