ABSTRACT

Anal intercourse (AI) among heterosexuals is an understudied and taboo subject. This 2017 Swiss national study aimed to describe the characteristics and motivations of heterosexual young adults practicing AI. Participants with any same-sex experience, same-sex attraction or non-heterosexual identity were excluded. The Federal Statistical Office provided the initial sample and potential participants were recruited through postal mail inviting them to an online survey (response rate 15.1%). The sample comprised 3892 participants (52% males; 54% of the overall sample, mean age 26.3 years). Overall, 55% of women and 56% of men had never experienced AI, 17% and 12% had done it once and 28% and 32% more than once, respectively. We found that participants engaging in AI had higher odds of practicing intercourse while intoxicated, being younger at first sexual experience, not using a condom at last intercourse and reporting a history of sexual transmitted infections. The main reason reported by both genders for engaging in their first AI was being curious followed by being in love. In conclusion, AI is a widespread practice among heterosexual young adults and health professionals should be especially attentive to it.

摘要

异性恋者之间的肛交 (AI) 是一个研究不足和禁忌的话题。这项 2017 年瑞士国家研究旨在描述异性恋年轻人练习人工智能的特征和动机。排除具有任何同性经历、同性吸引力或非异性恋身份的参与者。联邦统计局提供了初始样本，并通过邮寄方式招募了潜在参与者，邀请他们参加在线调查（回复率为 15.1%）。样本包括 3892 名参与者（52% 男性；占总样本的 54%，平均年龄 26.3 岁）。总体而言，55% 的女性和 56% 的男性从未体验过人工智能，17% 和 12% 曾经做过一次，28% 和 32% 分别做过一次以上。我们发现参与人工智能的参与者在醉酒时进行性交的几率更高，第一次性生活时年龄较小，最后一次性交时不使用避孕套，并报告有性传播感染史。两性报告的第一个人工智能参与的主要原因是好奇，其次是恋爱。总之，人工智能是异性恋年轻人中的普遍做法，健康专业人士应该特别注意它。
