The pain in the abdomen after masturbation is considered to be the contraction of the uterus caused by the orgasm during masturbation, and the contraction of the uterus can easily cause mild abdominal pain, which is normal. If the pain is severe and accompanied by increased vaginal discharge and abnormal leucorrhea, it is considered to be caused by vaginitis, pelvic inflammatory disease, endometritis, etc. You can go to the hospital for ultrasound, routine leucorrhea examination, and colposcopy. If there is no gynecological inflammation, there is no need to worry. Pay attention to abstaining from masturbation, which often causes gynecological infections and also urinary tract infections, and can cause low libido in serious cases. The actual fact is that you will need to use antibiotics under the guidance of a doctor, such as ofloxacin, and also cephalosporin and other drugs, not to masturbate and have intercourse during treatment, which can easily aggravate the condition.
