Can inflammatory bowel disease affect your sex life?

Yes. Certainly if you don't feel well, have pain, diarrhea, bleeding can put a damper on sex life. Fistulas (abnormal connection between loop of bowel and something else-bowel, bladder, vagina, outside world) definitely can affect sex life. Meds like steroids can affect. Sulfasalazine can decrease sperm count. Ostomies can be a challenge.
Not really. Ibd should not affect your routine sex life but can have an impact during a 'flare-up'.
