Since 2008, the share of men younger than 30 reporting no sex has nearly tripled, to 27%

For most of the past three decades, 20-something men and women reported similar rates of sexlessness. But that has changed in recent years. Since 2008, the share of men younger than 30 reporting no sex has nearly tripled, to 28 percent. That's a much steeper increase than the 8 percentage point increase reported among their female peers.
