The percentage of adults in the US who have had sexual encounters with someone from their same gender doubled since the 1990s, a new study found.
The spike in same-sex hookups coincides with higher acceptance rates of same-sex sexuality among all generations — though millennials were found to be the most accepting, according to research published in the journal, Archives of Sexual Behaviour.
A team of scientists from San Diego State University, Florida Atlantic University and Widener University examined data from the General Social Survey, which asked more than 30,000 adults about their attitudes about same-sex behaviour since 1973, as well as their sexual partners since 1989.
The scientists found that, between 1990 and 2014, the percentage of men who have hooked up with at least one man rose from 4.5% to 8.2%. Furthermore, the percentage of women who have had same-sex experiences hiked up from 3.6% to 8.7%.
Additionally, the percentage of adults having sex with both genders increased from 3.1% to 7.7%, the study found.
Millennials, which are classified in the study as adults between the ages of 18 and 29 during the 2010s, reported the highest percentage of same-sex encounters, with 7.5 % of men and 12.2% of women saying they have had such experiences.
The scientists found that lesbian experiences were more likely to happen while women were young, whereas age wasn’t a factor in male gay encounters.
The study also determined that Americans are, by and large, more accepting of same-sex hookups. Between 1990 and 2014, the percentage of adults who believed “sexual relations between two adults of the same sex [was] not wrong at all” increased from 13% to 49% — including 63% of Millennials.
“These large shifts in both attitudes and behaviour occurred over just 25 years, suggesting rapid cultural change,” lead study author Jean Twenge, of San Diego State, said in a statement.
