The subject of heterosexual anal sex has attracted relatively little attention when compared the research and sex statistics that have been compiled regarding anal sex between men.In the mid 2000s, there were widespread media accounts that both youths and adults were engaging in more heterosexual anal sex than ever before. Most of these accounts were without any reliable data to back them up. The notion that heterosexual anal sex was on then increase was fuelled by a growing trend since the late 1990s for more anal sex in porn.
In his paper on the history of heterosexual anal sex, Bruce Voeller (Archives of Sexual Behaviour, 1991) set out how for decades doctors, psychiatrists, and researchers from all disciplines conspired to keep silent about heterosexual anal sex. Despite a great number of anecdotal resources, and statistics going back as far as the early Kinsey data from the late 1930s, talk of heterosexuals engaging in anal sex has been scarce, and reporting on the relevant data almost non-existent. Bruce Voeller suggests that this is, among other things, tied to taboos about anal sex, and homophobic beliefs that anal sex is only the domain of gay men. For this reason there are not nearly as good data on heterosexual anal sex as there is on other forms of heterosexual behaviour.
The early Kinsey data collected between 1938-1963 found that 9 percent of non-married males and 28 percent of non-married females reported that they had engaged in anal sex at least once. Among married subjects, the numbers were much lower--around 11 percent for both men and women. In 1974, Playboy magazine published a survey of over 2,000 people. Depending on the age of the respondent, between 14 and 25 percent of people said they had tried anal sex at least once. In a 1996 survey of Swedish women aged 18 to 74, about 20 percent of women overall reported having engaged in anal sex; this was mainly those in their middle years. More recent data from a national US representative sample comes from the 2002 National Survey of Family Growth which was conducted on over 12,000 men and women aged 15 to 44. The results show that 34 percent of men and 30 percent of women unmarried men and 28 percent of unmarried women in the early Kinsey data to a high of 34 percent of men and 30% percent of women in a national US survey in 2002. However, t is difficult to know how much of this reflects a real increase in heterosexual anal sex and how much is simply an increase in reporting that particular sex act.
Is Heterosexual anal sex more popular or just more socially acceptable and thus easier to report This is a key question, and one that the current statistics cannot fully answer. However, they do suggest that a generational change has occurred, where people born in the 1980s and later may be more comfortable admitting to having anal sex, or more interested in having anal sex, and find it easier to talk about and report on.
