The Wayne James Continuum of Human Sexuality: Two-Thirds of the Human Population is Bi-Sexual to One Degree or Another

Sex and sexuality figure significantly in any gentleman’s life; and having a positive, healthy outlook about one’s individual sexuality engenders overall happiness, which is the foundation for gentlemanly comportment.

Sexuality is an organism’s natural inclination towards engaging in sexual activity. Human sexuality manifests along a spectrum, from those exceedingly rare individuals who are 100% heterosexual and can only conceive of sexual intercourse if it is with the other sex, to those extremely rare individuals who are 100% homosexual and are utterly repulsed by the thought of sexual activity unless it is with someone of the same sex. Then halfway between those two very rare extremes are those über-rare persons who are 100% bi-sexual, equally comfortable engaging in intimate acts with one sex as with the other—and sometimes with both, simultaneously. Most people, however, fall somewhere within those three absolutes, gravitating either towards the heterosexual pole, the homosexual pole, or the bi-sexual median. For many 21st-century individuals who have truly observed, explored, and understood sexuality, sexuality is no longer viewed in over-simplified, absolute terms of “gay or straight,” the former being an “abomination,” and the latter being “correct.” Instead, today’s social thinkers see human sexuality as a complex, visceral, involuntary positioning along  a highly nuanced continuum, with no assignment of  “rightness” and “wrongness” or “naturalness” and “unnaturalness” attributed thereto. For those newly enlightened people, sexuality is an individualized expression of an oftentimes inexplicable penchant—the way people, for whatever reason, have favorite colors, fragrances, or foods, or naturally gravitate towards the arts or technology or athletics, for example. To such persons, all self-realized, harmless sexuality is valid, and to deny humans their fundamental right to fully and honestly express themselves sexually is to deny humans their basic humanity. For some other people, however, the only “valid” or “natural” expression of sexuality is heterosexuality, every other expression regarded as aberrant.


Many people—even in anonymous and/or confidential circumstances—tend not to respond truthfully to questions pertaining to sex and sexuality, partly because many people fundamentally regard such questions as overly invasive, and also, amongst other reasons, because many people are not fully aware of their own sexuality so as to be able to respond completely and precisely.

 Absent reliable empirical data or any objectively accurate method of qualifying and quantifying human sexuality, then, it is valid to postulate that most people, consistent with the established principles of “averages” and “medians,” are situated somewhere around the middle point on any continuum pertaining to humans.   Thus, on a Continuum of Human Sexuality, homosexuality on one pole and heterosexuality on the other, with bisexuality as the median, it is safe to surmise that the average person is situated somewhere towards the bisexual median.

An analysis of the Deconstruction of The Wayne James Continuum of Human Sexuality illustration reveals that only a miniscule percentage of the human population is 100% heterosexual, 100% homosexual, or 100% bisexual—that for the vast majority of people, sexuality contains “gray areas.” The illustration also reveals that bisexuality and its various gradations—traditionally regarded as the least representative of the three major categories of human sexuality—is, in actuality, by far the most representative: Approximately 66% (two-thirds) of the total human population is bisexual or a gradation thereof, with heterosexuality and its gradations and homosexuality and its gradations together accounting for the remaining 33% (one-third) of the overall population.  As such, The Wayne James Continuum of Human Sexuality model represents a significant departure from the conventional model, which traditionally suggests that approximately 96% of the human population is heterosexual, with homosexuality and bisexuality together accounting for the remaining 3%.  [Approximately 1% of the human population is categorized as asexual, thereby having no or very little sexual attraction or interest in sexual activity].


[Dr. Alfred Kinsey’s famous Kinsey Report (1948) concluded that human sexual behavior occurs on a seven-point spectrum (“The Kinsey Scale”), with 0 representing 100% heterosexuality and 6 representing 100% homosexuality. While Kinsey concluded that only a minute percentage of the human population could be categorized in one degree or another as bisexual, he also concluded that 37% (adjusted in 1979 to 36.4% by Kinsey’s successor, Paul Gebhard) of adult males in the United States had achieved orgasm as a result of sexual contact with another male—i.e., 37% of men had engaged in both heterosexual and homosexual activities. Based on 21st-century definitions, men who engage in both heterosexual and homosexual activities; “men who have sex with men”; and men on the “down-low” are all categorized as bisexuals.

Some of the inherent, fundamental problems with statistical findings regarding human sexuality is that they rely on self-report data (which tends to prove problematic when seeking sensitive information); and the studies tend to pose two types of questions (questions pertaining to same-sex sexual experiences and attractions, and questions pertaining to personal self-identification as “heterosexual,” “homosexual,” or “bisexual,” the results always yielding inconsistencies between test-subjects’ self-identifications and their experiences/attractions). Then, further complicating statistical data is the varying cultural perceptions of the definitions of “gay,” “bisexual,” and “heterosexual.” In much of Latin America, the Caribbean, and Africa, for example, a male who performs the “active” role (the person penetrating) does not necessarily self-identify as homosexual or bisexual).

Since the 1980s, but especially since 2000, countries all over the world have conducted male human sexuality studies—all of which have been criticized in one way or another, but typically on grounds of methodology, unreliability due to self-reporting/self-identifying, insufficient sampling, biased sampling, etc.—with the general conclusion that the homosexual and bisexual populations combine for a total of less than 5% of the human population: Canada, 1% homosexual, 1% bisexual (1988); Norway, 3.5% had had same-sex experience in their lifetime (1988); Denmark, 2.7% of men had had homosexual intercourse (1992); The Netherlands, 1.5% self-identified as gay, 0.6% self-identified as bisexual, 97.9% as heterosexual (2001)/3.6% gay, 5.5% bisexual, but 9.9% reported at least some same-sex attraction (2009); France, 4.1% of men had sexual intercourse with a man at least once in their lives (1992)/ 6.6% homosexual, 3.6% bisexual, 90.8% heterosexual (2011); Italy, 2.4% of population homosexual or bisexual (6.7% reported having had sex or having fallen in love with someone of the same sex), 77% heterosexual, 4% “other,” 15.6% did not respond (2011); Ireland, 2.7% self-identified as homosexual or bisexual/7.1% reported having had a homosexual experience (2006); Israel, 8.2% of Israeli Jews self-identified as gay or bisexual/11.3% self-reported same-sex attraction (2015); United Kingdom, 5.5% gay, 2.1% bisexual, 88.7% heterosexual, but 72% of all adults identify as 100% heterosexual, and 46% of adults between the ages of 18 and 24 describe themselves as 100% heterosexual (2015). Also, a 2012 study conducted by Cornell University’s College of Human Ecology found that 9% of men identified themselves as “mostly heterosexual.”

Even today, the general—even if shifting—consensus amongst people born before 1990 is that heterosexuality is the only “norm,” approximately 96% of the human population self-identifying as such. To maintain that position, however, is to defy both logic, common sense, observation of human behavior, and the long-accepted principles of “averages” and “medians” : Both heterosexuality and homosexuality are narrowly defined, exclusive categories; whereas bisexuality is a broadly defined, inclusive category, absorbing peripheral members of both the heterosexual and homosexual categories. It is highly unlikely, then, that bisexuality would be the least representative of the three categories. And if most people are “average”–as is the case with height, weight, intelligence, generosity, penis size, beauty, and everything else pertaining to humans that occurs on a continuum–and “average” on a continuum of human sexuality equates with bisexuality, then the necessary conclusion must be that most people are bisexual].
