But why is the prevalence of sexual minorities of interest at all? Does it matter how many people are gay, lesbian, bisexual, straight, or asexual? Yes, it does—both to scientists and nonscientists alike, and for a variety of reasons. One scientific reason is that sexual orientation is a fundamental aspect of human variability, and thus understanding the prevalence of heterosexuality, bisexuality, homosexuality, and asexuality helps to map the distribution of human sexual variability. Second, the prevalence of sexual minorities is of interest to groups who want to use the figures to support a political cause or a social issue. For example, some anti-gay groups are interested in the rate of homosexuality (particularly if it is low) to try to demonstrate that homosexuality is statistically rare and thus gay people should be considered abnormal, pathological, or at least a fringe element of society.[17] In contrast, gay, lesbian, and asexuality advocacy groups are interested in the rate (particularly if it is high) to demonstrate the opposite: that being a sexual minority is not uncommon or statistically abnormal, and that sexual minorities form a significantly large segment of society. A third reason why the sexual minority prevalence rate is of interest is because of the science of demography. As mentioned in the introduction (chapter 1), demographers are interested in how many members of sexual minorities there are, because their prevalence relates to, among other things, trends in marriage and fertility (how many people marry and/or have children). Fourth, the prevalence of sexual minorities relates to physical health issues and, thus, is of interest to epidemiologists and health-care workers. A recent example concerns male homosexuality and the HIV/AIDS pandemic. HIV/AIDS in Western societies has been largely related to male-male sexual contact. As such, understanding the prevalence of male homosexuality can help with understanding the causes of this disease and tracking changes in it in Western societies. Indeed, some of the national probability surveys of human sexuality mentioned above (e.g., NATSAL-I, NHSLS) (Johnson et al., 1994; Laumann et al., 1994) were funded by government agencies wanting accurate information on people’s behavior as it relates to HIV/AIDS. Fifth, prevalence rates of sexual minorities are also important from a mental health perspective. As many people are aware, discrimination against gays, lesbians, and bisexuals is still a societal problem (Herek, 2000; Herek, 2002). Moreover, the “coming out” process is often stressful for sexual minorities. For example, one study found that a very high percentage of gay men (approximately 90 percent) felt troubled, many “extremely so,” when coming out to their parents (D’Augelli, 1991). But what about asexuals—are they also subject to discrimination and to significant stress in coming out? There is much less research on this issue but, interestingly, there is recent evidence that asexual people may, in fact, be viewed more negatively than gays, bisexuals, and lesbians (see more in chapter 7) (MacInnis & Hodson, in press). Thus, accurate knowledge of sexual minority prevalence rates helps workers in mental health care gauge the size of, and potentially address, this mental health concern facing society.
In the final part of this chapter, I explore people’s reactions to the idea that a certain percentage (e.g., 1 percent) of humanity is, in fact, asexual, including the “As if!” reaction mentioned earlier.
At the outset, though, let me offer one qualification. Despite the “As if!” reaction introduced this chapter, I do not want to leave the reader with the impression that all people have reacted with disbelief—many, if not most, people have seemed to accept that a small minority of humanity is asexual. Also, as I will discuss later in the chapter, some have actually indicated surprise that the original figure (1 percent) is so low. Relatedly, my sense is that some people have reacted with relief to the suggestion that a certain percentage of humanity is asexual.
But let’s come back to the doubters and deconstruct the “As if!” reaction: Why do some people feel that less than 1 percent of the population is asexual, and who exactly are these doubters?
