According to some research, this isn’t as crazy as it sounds. A 2009 study found that, when you compare typical condom use to typical use of the pullout method (rather than the ideal usage of each), the withdrawal method is only slightly more likely than condoms to result in pregnancy. A recent survey conducted by the delightfully named Dr. Annie Dude, a researcher at Duke University, found that almost a third of women between the ages of 15 and 24 have relied on coitus interruptus as a birth-control method. A slew of disappointed articles followed. “Ladies, I implore you: Get on some real birth control,” wrote Janelle Harris at Clutch magazine. Slate’s Amanda Marcotte called the findings “worrisome.” Venerated sexpert Dr. Ruth Westheimer has compared the pullout method to Russian roulette, and clarified that the research mostly proved how often condoms are misused, not how safe withdrawal is.
