Seminal emission is normal for a 30-year-old man. 30-year-old men also have many who are not married, do not have regular sexual intercourse, and do not masturbate, and thus have no reasonable sexual release. The sperm is constantly produced every day, the sperm produced through the epididymis, vas deferens, stored in the seminal vesicle, no reasonable sexual release for a long time, semen stored in the seminal vesicle to a certain amount, the penis erect at night after excitement, semen will automatically overflow, this is the phenomenon of spermatorrhea. Many men are busy at work and can’t have reasonable sexual release for a long time, and frequent seminal emission can occur after mental tension or excessive fatigue, so seminal emission is normal for 30-year-old men and there is no need to worry.
