Receptive Anal Intercourse: Impact on Colorectal and Urologic Diagnoses.

Purpose: We evaluated the relationship between lifetime receptive anal intercourse (RAI) and the risk of common colorectal and urologic diagnoses. Methods: We conducted an internet-based survey on sensations during RAI between July 2022 and March 2023. We used multivariable logistic regression to assess the independent impact of lifetime RAI exposure on the diagnosis of common urologic and colorectal conditions. Participants completed a main survey and were invited to complete randomly assigned patient-reported outcome measures (PROMs), which measured pelvic symptoms, mental health symptoms, and sexual satisfaction. Results: In total, 1100 participants completed the main survey and 416 completed the PROMs. Participants of the main survey ranged from 18 to 78 years old and the median age of the sample was 32 years. There was no significant association between lifetime RAI exposure and any medical diagnosis, except for anal fissures, which increased linearly with additional RAI exposure. Both sexual satisfaction and mental health symptoms improved with RAI exposure. Conclusions: RAI was not associated with most of the colorectal and urologic diagnoses tested and was associated with fewer mental symptoms and increased sexual satisfaction. Development of anal fissures may be directly related to trauma of the anal canal from penetration.
