Irregular Bowl Movements

Published: May 14, 2012
Dear TeenHealthFX,


I've been having anal sex with my girlfriend and after she says that her bowl movements have been irregular. Is this normal, and is there cause for immediate attention?

Dear Irregular Bowl Movements,


Without knowing more specific information about the symptoms your girlfriend is experiencing, as well as the length of time she has been experiencing them, it is hard for TeenHealthFX to have a sense of whether or not her bowel irregularities are connected to the anal sex. Irregular bowel movements can be connected to medical issues, such as irritable bowel syndrome (IBS), poor diet (such a diet low in fiber), or even emotional health issues, such as anxiety and stress. If your girlfriend is concerned about her irregular bowels, FX would recommend that she meet with her primary care physician to discuss the issue. Your girlfriend should mention to the doctor that she does engage in anal sex and that the two of you should hold off on having anal sex until she has seen a doctor and has a better understanding about the cause of this issue.


FX is unsure exactly what you mean by irregular (she is constipated, has diarrhea, she goes too frequently or not frequently enough, etc.), but it possible for fecal incontinence to occur due to anal sex – though the risk is small. This occurs from repeated injury to the internal sphincter when the penis is repeatedly inserted through a contracted internal sphincter. Over time the muscle may be unable to properly seal tightly, resulting in fecal incontinence. 


FX would also like to stress that it is VERY important for the two of you to be taking precautions when having anal sex, such as wearing a condom. Keep the following guidelines in mind when practicing anal stimulation and intercourse:

·        If it hurts, don’t do it. 

·        Listen to your partners and respect their wishes. 

·        If you start to experience pain or notice blood, stop immediately. 

·        Always use safer-sex devices such as condoms, gloves or finger-cots.  Finger-cots are devices resembling male condoms, typically used to cover cuts and open wounds on fingers.  They are usually found in the wound care and bandage section of the drug store.

·        Use a new latex condom with each sexual act if alternating between anal and vaginal sex.

·        Do not pass sex toys back and forth between partners. 

·        Avoid fisting and inserting very large sex toys into the anus.

  • If complications arise, visit an understanding healthcare provider.


If you don't have a doctor and live in northern New Jersey, you can call the Adolescent/Young Adult Center for Health at 973-971-6475 for an appointment or contact your local teen health center or Planned Parenthood.
