The lifetime of anal intercourse increased from 27% to 36%. It has been widely assumed to be one of the major causes of fecal incontinence. Heterosexual anal intercourse is rarely discussed in the scientific literature. In this descriptive cross-sectional observational study, we reviewed fecal incontinency in patients who came to Tehran Legal Organization from January to November 2019 and have complaints of AnoReceptive Intercourse(ARI). The mean age of patients was 29.18±10.5 years old. The mean Wexner score was 4.78±4.6. The most common type of anal intercourse was unwanted (47%). Thirty-two patients of 40 patients had a gap in their external anal sphincter in endo anal sonography. Stool consistency divided into 3 groups as the most common was soft (70%). There was also no difference in Wexner score between patients who had gaps in their ext anal sphincter and those who had not. In this study we understood the prevalence of gap is high among patients with ARI (82.6%) and the most common form of incontinency was to a liquid form of stool, although the mean Wexner score is 4.7 in this group
