This study examines the frequency and duration of pain in same-sex anal intercourse in a sample of 277 adult men who have engaged in, or attempted to engage in, anal intercourse during their lifetime. Whereas estimates of frequency of pain appeared blocked distributed across a 7-point Likert scale, severity of pain appeared positively skewed, with 12% rating it as too painful to continue. Participants rated inadequate lubrication, psychological factors such as not feeling relaxed, and lack of digitoproctic stimulation prior to penetration as the three most important psychophysiological factors predicting pain. Factors associated with a greater amount of pain experienced in anal intercourse were depth and rate of thrusting, lack of social comfort with gay men, being more "closeted," and less concern over becoming old or unattractive as a gay or bisexual man. Pain was also positively related to anxiety. The use of condoms was not rated highly as a factor in receptive anal pain. Based on these findings, the authors define anodyspareunia to denote painful receptive anal intercourse, and suggest clinical criteria similar to that used for other sexual pain disorders.
本研究对277名成年男性进行了抽样调查，这些男性一生中曾进行过或试图进行过肛交，研究考察了同性肛交中疼痛的频率和持续时间。疼痛频率的估计值在7点李克特量表上呈现出阻塞分布，而疼痛严重程度则呈正偏态分布，12%的人认为疼痛过于剧烈而无法继续。参与者将润滑不足、心理因素（如感觉不放松）以及插入前缺乏指肛刺激评为预测疼痛的三个最重要的心理生理因素。与肛交中经历更多疼痛相关的因素包括插入深度和速度、与男同性恋者缺乏社交舒适度、更“隐蔽”以及作为男同性恋或双性恋男性对变老或失去吸引力的担忧较少。疼痛也与焦虑呈正相关。避孕套的使用在接受性肛交疼痛方面未被高度评为一个因素。基于这些发现，作者定义了“肛门性交疼痛障碍”来表示接受性肛交疼痛，并提出了与其他性疼痛障碍类似的临床标准。
