Except they don’t. Even with age controlled, GenX’ers born in the 1970s report having an average of 10.05 sexual partners in their lifetimes, whereas Millennials and iGen’ers born in the 1990s report having sex with 5.29 partners. So Millennials and iGen’ers, the generations known for quick, casual sex, are actually having sex with fewer people—five fewer, on average. As Figure 8.3 shows, men born in the 1990s had nine fewer partners than those born in the 1970s, and women had about two fewer.
