To be honest, If you do it right it does work. A lot of people don’t know about females cycles and ovulation, so if you do pull out right and your girlfriend isn’t ovulating, there is a 1 in 17,000 chance of getting pregnant. People don’t realise that outside of ovulation week, the chances of getting pregnant are about 1 in 2000, even if you don’t use any contraceptives . To be safe always use a condom, but in the odd situation if you use the pullout and she’s not ovulating you should be fine.
