From the modesty debate to the mainstreaming of 
“twerking,” the American public has a complex relationship with sex. 
Ever since the sexual revolution of the 1960s, the liberalization of 
social and moral attitudes toward sex has met with a conservative 
backlash troubled by the impact of an increasingly sexualized culture.
So what do Americans think about sex? What is its purpose, and where 
should we have it? And what do people think about traditional sexual 
ethics? Are they outdated? In a recent study, Barna Group asked about 
these and other questions related to sex—and discovered there is no 
broadly shared consensus among American adults.
Half of U.S. adults (50%) agree strongly that “choosing not to have 
sex outside of marriage is healthy.” But generational differences are 
significant. Six in 10 Elders (59%) agree strongly with this statement, 
compared to 53 percent of Boomers, 49 percent of Gen-Xers and 43 percent
 of Millennials.
Practicing Christians (72%) are almost twice as likely as adults of 
no faith (38%) to say that choosing not to have sex outside marriage is a
 healthy choice. Women (56%) are more likely than men (43%) to hold this
 view. Compared to those who have never been married (41%), people who 
are married (53%) and, somewhat surprisingly, cohabitating adults (49%) 
are more likely to strongly agree with the statement.
It may be that these differences of opinion spring at least in part 
from confusion or ambivalence about the purpose of sex. When U.S. adults
 are asked to choose one or more phrases from a list of options that 
summarizes what sex is for, not everyone agrees.
Among all American adults, the most common answers given when asked 
about the purpose of sex were “to express intimacy between two people 
who love each other (63%), “to reproduce / to have children” (60%), and 
to connect with another person in an enjoyable way (45%).
There are disparities, for instance, between generational cohorts. 
Overall, Elders and Boomers tend to share a stronger consensus about the
 purpose of sex. That is, clear majorities among the older generations 
say sex is for procreation (79% Elders; 71% Boomers), expressing 
intimacy between two people who love each other (68% Elders; 73% 
Boomers) or uniting a man and woman in marriage (62% Elders; 50% 
Boomers).
The two younger adult generations are much less likely to embrace 
these traditional views of sex. Most Gen-Xers and Millennials continue 
to believe conventional ideas of sex: that it is to express intimacy 
between two people who love each other (57% Gen-Xers; 56% Millennials) 
or to procreate (52% Gen-Xers; 51% Millennials). However, the notion 
that it should unite a man and woman in marriage is endorsed by just 
one-third of Xers and Millennials.
Nearly half of younger generations say that sex is to connect with 
another person in an enjoyable way (44% Gen-Xers; 49% Millennials), 
though this sentiment is not much different from older adults. Notably, 
Millennials are much more likely than older adults to say the purpose of
 sex is self-expression and personal fulfillment (41%).

Gender seems to play a role in one’s view of sex. Seven out of 10 
women (69%) say the purpose of sex is to express intimacy, but a smaller
 majority of men, 57 percent, believe the same. Conversely, men are more
 likely than women to indicate sex unites a man and woman in marriage 
(45% men; 39% women) or satisfies a biological need other than 
procreation (43% men; 36% women).
Practicing Christians (56%) are more than twice as likely as those 
with no faith (25%) to say the purpose of sex is to unite a man and 
woman in marriage. At the same time, those with no faith are much more 
prone than practicing Christians to say sex is for connecting with 
another person in an enjoyable way (60% no faith; 36% practicing 
Christians) or for self-expression or personal fulfillment (46% no 
faith; 26% practicing Christians). There are also notable differences 
between these groups and Americans who identify with a religious faith 
other than Christianity. For instance, those of other faiths consider 
marriage as at a higher rate (32%) than the other groups (23% no faith; 
15% practicing Christians), or to satisfy a biological need, (46%), 
comparatively (33% no faith; 32% Practicing Christians).
 Traditional Sexual Ethics: Moral, Good and Unrealistic
Traditional Sexual Ethics: Moral, Good and Unrealistic
Barna asked American adults their opinion of traditional Christian 
sexual ethics, which teaches “that sex should only be within a marriage 
between a man and a woman.” Among all adults, the top five descriptions 
of this phrase are “moral” (36%), “good” (28%), “healthy” (27%), “right”
 (27%) and “unrealistic” (22%). The rest were “anti-gay” (16%), “too 
strict” (13%), “repressive” (13%), “virtuous” (12%), “unenlightened” 
(9%), “wrong” (7%), and “damaging” (6%).
Generationally, there is again greater consensus among older adults 
than among younger Americans on this matter. The top five descriptions 
among Gen-Xers and Millennials are similar to their older counterparts, 
but smaller proportions share the traditional point of view on 
traditional Christian sexual ethics. For example, “moral” is the 
number-one choice of both Millennials and Elders, but the younger cohort
 (26%) is half as likely as their elders (51%) to choose this option. 
Also, Millennials were the only generational segment that had “anti-gay”
 (19%) in their top five, as well as the only one missing “right” (16%) 
from their top five.

Unsurprisingly, Christians hold more positive opinions than 
non-Christians when it comes to traditional Christian sexual ethics. On 
the other hand, adults who say they are not believers (that is, they are
 atheists, agnostics or unaffiliated) view the statements on Christian 
sexual ethics in a distinctively negative light: Just 11 percent believe
 traditional ethics are “moral,” and that definition ranks ninth among 
their preferences—the highest of all positive descriptors. Otherwise, 
non-believers say that such sexual ethics are unrealistic (36%), 
anti-gay (27%), repressive (25%), too strict (17%), or that they aren’t 
sure what to make of it (17%).
What’s interesting is that people who hold to faiths other than 
Christianity, such as Jews, Muslims, Buddhists, and so on, are likely to
 embrace a mix of favorable and unfavorable views of traditional sexual 
ethics. Their top five descriptors includes moral (28%), right (26%), 
anti-gay (24%), unrealistic (22%), and good (21%).
 What the Research Means
What the Research Means
Roxanne Stone is editor in chief at Barna Group and says that the 
research shows the collision of new and old attitudes about sex in 
society today. “The big story here is how little everyone agrees on when
 it comes to the purpose of sex,” says Stone. "There’s never been a 
shortage of conversations and cultural imagination around sex, but this 
current lack of consensus points to a growing ambiguity and tension over
 its place in society and in the individual’s life.
“Of course, the greatest divides are where you’d expect them,” notes 
Stone. “Between people of faith—especially Christians—and the broader 
population. And between younger and older generations. Whereas 
practicing Christians still overwhelmingly tie sex to marriage, the move
 among the greater U.S. population—most evidently among younger 
generations—is a de-linking of marriage and sex. Sex has become less a 
function of procreation or an expression of intimacy and more of a 
personal experience. To have sex is increasingly seen as a pleasurable 
and important element in the journey toward self-fulfillment.
"It is impossible to separate this shift from other cultural trends, 
most notably the delay of marriage,” continues Stone. "The age of first 
marriage has climbed into the late twenties for both men and women. 
This, dovetailing with a popular and increasingly assumed narrative of 
sex as a normal part of the single life, makes the case for saving sex 
until marriage a radical one.
“It’s important for Christian leaders to notice this shift in the 
framing of sex and to adjust their own conversations accordingly,” says 
Stone. "If sex is being viewed as an individualistic act of 
self-expression and personal fulfillment—then how can leaders both 
acknowledge the ways sex does help us grow as individuals, but also 
offer a counter-narrative that emphasizes the sacrificial nature of love
 and intimacy? If a significant (albeit decreasing) number of young 
adults still view sex as an avenue toward intimacy—then how can leaders 
celebrate that desire, while offering reasons to reserve that level of 
intimacy for marriage? The views toward the meaning of sex revealed in 
the research can help Christian leaders frame their conversations about 
sex toward the real perspectives and pain points Americans—especially 
young adults—are feeling toward the topic."

About the Research
The study on which these findings are based was conducted via online 
surveys from August 24 to August 26, 2015. A total of 1,000 interviews 
were conducted. The sample error is plus or minus 3.0 percentage points 
at the 95-percent confidence level. The completion rate was 71 percent.
Minimal statistical weighting was used to calibrate the sample to 
known population percentages in relation to demographic variables. The 
online study is derived from a probability panel, which means that 
respondents are recruited for inclusion in the research based on 
physical mailing addresses, not an opt-in online panel. Those randomly 
selected households without Internet access are provided an 
Internet-enabled device to complete surveys.
Generations: Millennials are the generation born 
between 1984 through 2002; Gen-Xers, between 1965 and 1983; Boomers, 
between 1946 and 1964; and Elders, in 1945 or earlier.
“Other faith” indicates respondents who self-identify with a religion other than Christianity.
“No faith” indicates respondents who self-identify as atheist or agnostic, or who are religiously unaffiliated.
“Practicing Christians” are self-identified Christians who have 
attended a church service in the past month and say their religious 
faith is very important in their life.
