Abstract
Background: There is limited research about the prevalence of receptive anal intercourse (RAI), erogeneity and sexual pleasure within the zones of the rectum. Aim: We describe the experience of RAI within a large and diverse population in an online convenience survey, to map zones of erogenous sensation within the rectum, and to assess orgasm function among individuals who practice RAI. Methods: Adult subjects were recruited from an online survey platform and were queried about their history of RAI. Those who endorsed RAI were shown illustrations of the rectum divided into four non-overlapping anatomic regions. Subjects designated regions where they experienced pleasure when touched during RAI. Subjects were also asked about their ability to achieve orgasm from RAI alone or if they required co-stimulation of additional regions. Demographics were collected, and differences were analyzed based on gender, age, and sexual orientation identity. Outcomes: Outcomes include mapped erogeneity of the rectum among men and women and self-reported experiences with RAI, including orgasm function related to RAI among cisgender adults. Results: < .05). Gay men and women were more likely to have participated in RAI. The superficial anterior rectum was the most frequently selected region by both men and women as a site of pleasure when touched during RAI. Clinical Implications: The results of this study will highlight preferred zones of erogeneity in the rectum, which could be impacted by surgeries or pathology in these areas. Strengths and Limitations: This study captured a comprehensive assessment of erogenous sensation within the rectum among a large sample. Limitations include the use of a online subjects for data collection, which can result in both response and selection bias. Conclusion: Our findings show that RAI is practiced by many adults across ages, gender, and sexual orientation identities. Both men and women report pleasure from various areas within the rectum, primarily the superficial regions of the rectum. These findings may prove helpful in elucidating practices of RAI. Additionally, understanding erogeneity in the rectum may allow providers to better predict changes due to pathology and treatments of or surrounding these areas.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
