Condom can fail.
Defective condom pass inspection.
Rascal poke hole in condom.
Very old condom.
Vaseline dissolve condoms.
Condom not withdrawn properly.
Condom worn after foreplay.
Condom foil cuts condom.
So condom is not 99.9% safe.
98% is more realistic.
That means if you screw 100 women, wearing a condom each time, two
of them will get pregnant despite the condom.
