10 dumb mistakes that can get her pregnant.. [Read]

9. The Mistake: You take the condom off before the sex is over. 

The Potential Damage: If you’re patting yourself on the back for using a condom in the first place… don’t. Taking a condom off too early on into sex “can directly compromise the efficacy of condom use,” according to a recent study from The Journal of Sexual Health. But you know that, silly! So if you play by the rules and keep that sucker on the entire time, it’s 98 percent certain (see no. 6) you won’t have to worry about becoming a daddy. (Just be sure you hold the base of the condom during withdrawal to make sure it doesn’t slip off or leak you-know-what.)
