Thanks for your query. Read your history and understood the problem. As per the history you have provided, your boyfriend rubbed the penis into your vagina, but you say there was no insertion. If no insertion, the chances of pelvic infection is remote, rather not possible. The cause of pain in your lower abdomen then can be due to :Enteritis, Any problem related to the Fallopian tubes or Ovary.PID-Pelvic Inflammatory disease if you had sex before. Appendicitis. I would advise you the following:Get blood and urine tests. Ultrasonography of the abdomen and pelvis to get an idea. Examination by a Gynecologist and or Surgeon to see for the probable cause. Start treatment with an antibiotic and metronidazole, probiotics and supportive and symptomatic treatment under the guidance of the Doctor.
