There is no difference between seminal emission and hand flushing masturbation in terms of outcome, but there are some differences in the way it occurs and the effects it has on the body. Both seminal emission and masturbation end up with ejaculation as the end result. Seminal emission is a phenomenon of involuntary overflow of sperm without either sexual intercourse or masturbation. Usually, seminal emission during sleep is called dream emission, while seminal emission in the waking state is also called slippery semen. Occasional seminal emission in adolescent males is a normal physiological phenomenon and often does not affect the body. The hand flush, also known as masturbation, is actually a form of masturbation in which the hand is repeatedly stimulated externally on the penis to achieve a state of ejaculation, accompanied by the pleasure of ejaculation. Moderate frequency of masturbation can relax, relieve mental stress and help improve the body’s immunity. But if you masturbate frequently for a long time it is likely to have a series of adverse effects on the body, such as premature ejaculation, ejaculatory dysfunction, impotence, etc. It will also leave the body in a state of fatigue, poor mental health, poor sleep, etc., thus affecting normal life and work.
