Whether it is normal for a man to ejaculate more than 30, should be analyzed specific to the problem. Seminal emission refers to the ejaculation of men in the absence of sex or sexual masturbation, often occurs at night, is a sign of male sexual maturity. For unmarried men who have not masturbated for a long time, or married men who have not had regular sex for a long time, seminal emission is a normal phenomenon and can generally occur 1-4 times a month. It should be decided according to each person’s physical condition and the amount of sexual stimulation. Therefore, for men in their 30s, if they are unmarried and do not have the habit of sexual masturbation, or if they are married and have not had regular sex for a long time, seminal emission is normal. If you are married and have a regular sex life but still have seminal emission, it may be caused by too much sexual stimulation or possibly prostatitis and vesiculitis.
