The legalization of same-sex marriage may have signified a massive change in the way our society accepts sexuality, but new research shows that Americans’ attitudes toward their own sexual experiences may be more open as well. The study found that more and more Americans — whether they’re straight, bi, homosexual, or transsexual — are accepting the idea of same-sex experiences, and have even partaken in them themselves.

In particular, the study finds that the percentage of American adults who’ve had sex with people of the same gender has doubled since the 1990s. And this rising acceptance of same-sex love has remarkably occurred across all generations, perhaps not surprisingly peaking with Millennials.

The study, published in the journal Archives of Sexual Behavior, used data from the General Social Survey, which has gathered information about 30,000 adults and their sexual partners since 1989. From 1990 to 2014, the percentage of men who reported having had sex with one or more men rose from 4.5 to 8.2 percent. That number increased from 3.6 to 8.7 percent for women. And the amount of people who reported having bisexual experiences also grew from 3.1 to 7.7 percent. Those numbers were generally higher when measured specifically in the Millennial group, with up to 7.5 percent of men and 12.2 percent of women having had same-sex experiences.

The second part of the study focused on Americans’ opinions about same-sex experiences, and analyzed data on that since 1973. From 1973 to 1990, the number of people who accepted same-sex intimacy basically stayed the same — but after 1990, it grew immensely, from 13 to 49 percent. And 63 percent of Millennials accepted same-sex involvement.

With greater openness and freedom in society regarding same-sex relations, many argue that it’s time to discuss the health issues pertinent to those groups. LGBT people, or even straight people who are experimenting, face specific health and safety issues that can be avoided with proper contraception and conversation. In the past, a fear of stigmatization, or homophobic health care professionals prevented many LGBT people from getting the right care or information, but society’s latest shifts may change that.

Research has shown that lesbian and bisexual women have a higher risk for breast and endometrial cancer, as well as cervical cancer. Gay men have a higher risk of eating disorders, STDs, and anal cancer, and transgender individuals face their own set of woes, particularly mental health issues. Wearing a condom or getting vaccinated can prevent various sexually-transmitted diseases, like hepatitis A or B, and HPV. For homosexual men, the drug Truvada can lower the risk of sexually-transmitted HIV for high-risk populations.

And because of the prejudice or discrimination LGBT individuals will likely face, depression and suicide risk is a major issue that needs to be addressed in these communities. According to SAMHSA, lesbian and bisexual women experienced more emotional stress as teens when coming out to parents and society and thus were 2 to 2.5 times more likely to think of suicide than heterosexual women.

The latest study suggests that open-mindedness and acceptance is only growing, and health care for LGBT groups also may improve. “These large shifts in both attitudes and behavior occurred over just 25 years, suggesting rapid cultural change,” said Jean Twenge, professor of psychology at San Diego State University and an author of the study, in a press release. “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.”
