Indiana University Study: Partnered Sex of All Kinds Declines in U.S.

Data collected between 2009 and 2018 indicates that both teens and adults in the United States are having less partnered sex than they used to.
“The researchers noted that a number of cultural and social changes may be affecting young people’s sexual behavior, including widespread internet access, decreased alcohol use, increased conversations around sexual consent, and more contemporary young people identifying with non-heterosexual identities, including asexual identities.”
