Preliminary data are presented on 53 urban Mexican males interviewed during 1970-1971 in a study of homosexual encounters in a large Mexican city. These data are compared with data from recent studies in the United States and England of male homosexual behavior. Although preliminary and limited, the Mexican data indicate that cultural factors are important determinants of life styles and sex practices of homosexual males. Forty-eight of the 53 (90%) preferred and usually practiced anal intercourse, four preferred oral contacts, and one preferred mutual masturbation. Interviewees were also grouped according to major type of sex activity during the first sustained year of homosexual activity after puberty. One intragroup comparison indicates significant differences between anal active and anal passive interviewees. For example, as children anal passive subjects had significantly more homosexual contacts with adults; they also considered themselves more effeminate and as children were more involved with female sex-typed activities. Comparison of data from the English and United States studies with the present data suggests that preference for a particular sexual technique is not as developed in the former two countries; when there is a preference, it is not usually for anal intercourse.
初步数据显示，在 1970 年至 1971 年期间，对 53 名居住在墨西哥城市的男性进行了采访，这些人在一项关于同性恋者在墨西哥大城市中相遇的研究中接受了采访。这些数据与美国和英国最近的男性同性恋行为研究数据进行了比较。尽管这些数据初步且有限，但墨西哥的数据表明，文化因素是同性恋男性生活方式和性行为的重要决定因素。53 名受访者中有 48 名（90%）更喜欢并经常进行肛交，4 名更喜欢口腔接触，1 名更喜欢相互手淫。受访者还根据青春期后同性恋活动的第一年中主要的性行为类型进行了分组。一项组内比较表明，肛交主动和肛交被动的受访者之间存在显著差异。例如，作为孩子，肛交被动的受访者与成年人有更多的同性恋接触；他们也认为自己更女性化，并且在儿童时期更多地参与女性性别认同的活动。将来自英国和美国研究的数据与目前的数据进行比较表明，在这两个国家，对特定性行为技术的偏好并不那么强烈；当存在偏好时，通常不是肛交。
