This doesn't work for everyone but I'm fairly responsible, and no accidental pregnancies, so it worked for everyone I was with. The same way went for my wife as well, and we have 2 kids now, with no accidentals ones. I'm going to teach my son this as well, that the responsibility is on both parties but as the man you need to control what you can control and don't leave things to chance, especially something as life changing/destroying as an accidental pregnancy.
