not wearing a condom is just plan dumb if you don't want a kid. Sure they can break or tear, but if you don't want a kid its the best thing you as a man can do to protect yourself aginst that. I'm sketched out even when a woman tells me she's on the pill. I make sure I wear a condom, a kid is that last thing I want in my life right now. there are no sure things, stuff happens. you need to protect yourself as much as you can if you don't want a kid. even if you get her on the pill there is no sure thing it will work completly. if you continue to have unprotected sex something is going to happen if your ready for the kid or not. your have already made the unconsious decision to have a kid by not protecting yourself.
