항문 성교: 두 판 사이의 차이

2004년 보고에 따르면, “몇몇 연구는 "미국의 4명의 동성애자들이 항문 성교를 가졌는데 한 명은 12번을 하였고 이는 간헐적이거나 우발적인 것이다.<!--One in four heterosexuals in the US has tried anal sex and for one in 12, it is an occasional or episodic practice.-->”라고 넌지시 알려준다. 또 다른 연구는 “남성 동성애자들이 항문 성교를 가지는 만큼 많은 여성들도 7번이나 가져 그 수치는 더 많은 전반적인 동성애자의 인구를 반영한다.<!--Seven times as many women as gay men engage in anal intercourse, a figure reflecting the greater overall heterosexual population.-->”고 밝힌다.<ref>Anne-christine d’Adesky, ''Expanding Microbicide Research'' in amfAR Global Link - Treatment Insider; May 2004</ref> <!--While at the present time it is reported more frequently among [[homosexuality|same-sex couples]], according to Dr John Dean and Dr David Delvin, "in absolute numbers, it is hypothesized that more heterosexual couples have anal sex than homosexual couples".<ref>" There is a common misconception that anal sex is practised almost exclusively by gay men. This is certainly not the case. It is thought that an estimated one third of gay couples do not include anal intercourse in their lovemaking. About one third of heterosexual couples try it from time to time. It is thought that about 10 per cent of heterosexual couples have anal intercourse as a regular feature of their lovemaking. In absolute numbers, it is hypothesized that more heterosexual couples have anal sex than homosexual couples. http://www.tiscali.co.uk/lifestyle/healthfitness/health_advice/netdoctor/archive/000594.html {{웨이백|url=http://www.tiscali.co.uk/lifestyle/healthfitness/health_advice/netdoctor/archive/000594.html |date=20070901183232 }}]</ref>-->
