 Among people who intend condoms to be their form of birth control , pregnancy may occur when the user has sex without a condom . The person may have run out of condoms , or be traveling and not have a condom with them , or simply dislike the feel of condoms and decide to " take a chance " . This type of behavior is the primary cause of typical use failure ( as opposed to method or perfect use failure ) .
