A man with prostatitis is harmful to his partner mainly because of sexual disharmony and gynecological inflammation. 1. Sexual disharmony. A man with prostatitis may experience symptoms such as impotence and premature ejaculation, which may cause sexual disharmony between the couple. 2. Gynecological inflammation. If you have bacterial prostatitis, there will be bacteria in the semen, which may be transmitted to your partner during intercourse, leading to gynecological inflammation such as vaginitis and pelvic inflammation. Men with prostatitis must be treated scientifically under the guidance of a doctor in a timely manner so as not to have a bad effect on their partners, and they should usually develop good hygiene habits.
