 And you thought the 70s were wild. 
 
 A new study finds that Americans are more accepting than ever before of same-sex canoodling. And not only do they think it’s okay — they’re trying it for themselves. 
 
 Nearly half — 49 percent — said "sexual relations between two adults of the same sex" was "not wrong at all" in 2014, a team of researchers from Florida Atlantic University, San Diego State University and Widener University found.

 They did not conduct the survey themselves, the team looked at the results of the General Social Survey, a large ongoing survey of around 30,000 U.S. adults conducted by the University of Chicago since 1972. 
 
 In 1973, just 11 percent of Americans said they thought homosexual sex was “not wrong.” By 1990 that percentage had risen just slightly, to 13 percent, the team wrote in the Archives of Sexual Behavior. 
 
 But in 2014, 49 percent of those surveyed said they had no problems with same-sex relations, and 63 percent of 18- and 19-year-olds felt that way. 
 
 And more people say they have had gay, lesbian and bisexual encounters. 
 
 “The number of U.S. adults who had at least one same-sex partner since age 18 doubled between the early 1990s and early 2010s (from 3.6 percent to 8.7 percent for women and from 4.5 to 8.2 percent for men),” the team wrote. 
 
 “Bisexual behavior (having sex with both male and female partners) increased from 3.1 to 7.7 percent, accounting for much of the rise, with little consistent change in those having sex exclusively with same-sex partners.” 
 
 A lot of the behavior appears to be experimental, the team said. 
 
 “Lesbian sexual experience is highest when women are young, suggesting there is some truth to the idea that some women are ‘lesbian until graduation’ or ‘bisexual until graduation,’ at least among younger generations such as Millennials,” said Florida Atlantic’s Ryne Sherman, an assistant professor of psychology who worked on the study. 
 
 “This pattern does not appear for gay (male) sexual experiences.” 
 
 The surveys suggest attitudes are changing most quickly in the South and Midwest and among whites. ||||| Abstract 
 
 We examined change over time in the reported prevalence of men having sex with men and women having sex with women and acceptance of those behaviors in the nationally representative General Social Survey of U.S. adults (n’s = 28,161–33,728, ages 18–96 years), 1972–2014. The number of U.S. adults who had at least one same-sex partner since age 18 doubled between the early 1990s and early 2010s (from 3.6 to 8.7 % for women and from 4.5 to 8.2 % for men). Bisexual behavior (having sex with both male and female partners) increased from 3.1 to 7.7 %, accounting for much of the rise, with little consistent change in those having sex exclusively with same-sex partners. The increase in same-sex partners was larger for women than for men, consistent with erotic plasticity theory. Attitudes toward same-sex sexual behavior also became substantially more accepting, d = .75, between the early 1970s and early 2010s. By 2014, 49 % of American adults believed that same-sex sexual activity was “not wrong at all,” up from 11 % in 1973 and 13 % in 1990. Controlling for acceptance reduced, but did not eliminate, the increase in same-sex behavior over time. Mixed effects (hierarchical linear modeling) analyses separating age, time period, and cohort showed that the trends were primarily due to time period. Increases in same-sex sexual behavior were largest in the South and Midwest and among Whites, were mostly absent among Blacks, and were smaller among the religious. Overall, same-sex sexual behavior has become both more common (or at least more commonly reported) and more accepted. ||||| It appears giving queer sex a whirl is becoming more popular -- or at the very least, more people are now willing to admit they've had a same-sex sexual encounter. 
 
 According to a study published Wednesday in the Archives of Sexual Behavior, the number of American adults who say they've had a same-sex experience has doubled over the last two and a half decades. 
 
 A press release sent to The Huffington Post by San Diego State University reveals that Jean Twenge, professor of psychology at SDSU, and colleagues Ryne Sherman of Florida Atlantic University and Brooke Wells of Widener University, found that "between 1990 and 2014, the percentage of men who reported having had sex with at least one man increased from 4.5 percent to 8.2 percent, and the number of women reporting having had sex with at least one woman increased from 3.6 percent to 8.7 percent." Twenge, Sherman and Wells also noted that "the percentage of adults reporting having had sex with both men and women rose from 3.1 percent to 7.7 percent." 
 
 The study was conducted by combing through the General Social Survey, which is a nationally representative survey that includes over 30,000 adults who've agreed to discuss their thoughts about a variety of topics including same-sex behavior, which the survey began recording in 1978, and sexual partners, which the survey has been documenting since 1989. 
 
 The press release also notes that the survey includes respondents' attitudes about same-sex relations. Twenge, Sherman and Wells found that "between 1973 and 1990, the percentage of adults who believed 'sexual relations between two adults of the same sex [was] not wrong at all' hardly budged, rising from 11 percent to 13 percent." However, since 1990, they found that acceptance has skyrocketed to "49 percent of all adults and 63 percent of Millennials in 2014." 
 
 “Millennials are markedly more accepting of same-sex behavior than GenX’ers were at the same age – but then, so are most adults,” Sherman said in a press release sent by Florida Atlantic University. “The change is primarily one of time period, where all adults shifted in their attitudes.” 
 
 Twenge added, "These large shifts in both attitudes and behavior occurred over just 25 years, suggesting rapid cultural change." She noted, "These trends are another piece of evidence that American culture has become more individualistic and more focused on the self and on equality. Without the strict social rules common in the past, Americans now feel more free to have sexual experiences they desire."
– The 2010s, baby. More Americans are opening up to the idea of same-sex experiences—and trying them out, according to a survey of 30,000 adults that's been ongoing since 1972. A year after the survey began, just 11% of participants thought homosexual sex was A-OK. By 1990, that figure had barely risen to 13%. As of 2014, however, 49% said "sexual relations between two adults of the same sex" was "not wrong at all," researchers explain in Archives of Sexual Behavior, per NBC News. Young Americans aged 18 and 19 were much more accepting, with 63% agreeing with the above statement. Though there was "little consistent change in those having sex exclusively with same-sex partners," the change in sentiment is apparently encouraging more Americans to change it up between the sheets, researchers say. Those who reported having at least one same-sex partner as an adult doubled between the early 1990s and early 2010s from 3.6% to 8.7% for women and 4.5% to 8.2% for men. The jump was even larger among whites and those in the South and Midwest. The number of Americans engaging in bisexual behavior rose from 3.1% to 7.7%. "These large shifts in both attitudes and behavior occurred over just 25 years, suggesting rapid cultural change," a study author says, per the Huffington Post. "Americans now feel more free to have sexual experiences they desire." One interesting tidbit: Women—particularly millennials—were most likely to have a same-sex experience at a young age, "suggesting there is some truth to the idea that some women are 'lesbian until graduation,'" a researcher says. No such trend was seen among men. (This study found almost a third of young Americans are bisexual.)
