Hi Doc, I am a 24 year old female. I ocassionaly masturbate, through clitorial stimulation. Not frequently, mostly once a month or twice- the days preceeding my monthly flow. For the past one year since I have been masturbating, I have noticed every month that after I masturbate- I experience pain in my abdomen. There has been one or two times with out the pain but normally, I do get abdominal pain. Is there cause for worry or is this normal? I have been a very active person. I don t drink or smoke. I am single and have never had sex before. I also do not excessively masturbate. So could you please help me out?
