by the General Social Survey, men between the ages of 18 and 29 are having less sex than ever; the number of abstinent men has nearly tripled in the last decade, from 10 percent in 2008 to 28 percent last year. But as Orenstein discovered, it’s a movement that exists largely in secret. Rather than declare their abstinence, they come up with excuses for their lack of sexual interest — like the college sophomore Orenstein interviewed who frequently faked “whiskey d–k” to avoid hookups, or Mitchell in Los Angeles, who avoided sex with his high-school girlfriend for years because he was terrified that his sexual ability “would just be … sufficient.” While girls struggle to find the magic middle ground between “prude” and “slut,” boys are “pushed to be as sexually active as possible,” Orenstein writes, “to knock out their firsts regardless of the circumstances or how they felt about their partners.” Enlarge ImageDavid Duchovny in "Californication" plays a womanizing novelist in Los Angeles.
