Americans Are Having Less Sex Than They Used To

Millennials aren’t just having less sex. They’re also marrying later. The average age for a first marriage was 27 for women and 29 for men in 2011, according to Pew. Statistically speaking, that’s an ideal age because couples who marry in their early 20s have a higher divorce risk than slightly older couples. (Still, the window is narrow, since the divorce rate starts to creep up again for couples in their mid-30s.)
