Patient's question:
Here is the translation of the provided text into English, with the specified requirements in mind:"Each time of sex lasts only a few minutes, sometimes twitching a bit and it's over. Had masturbation before."
Doctor's answer:
Masturbation itself does not cause any harm or adverse consequences. However, excessive masturbation is considered a psychological disorder and can severely affect physical health, leading to some urogenital diseases, sexual nerve exhaustion, and other issues. For most young people, masturbating more than once a week is considered frequent. Overly frequent masturbation can, on one hand, cause a decline in mental and physical energy, and on the other hand, excessive stimulation of the genital organs may lead to impotence, premature ejaculation, and potentially affect fertility.
