There's a way to force your Genes into all the women all the same, but without each of them making babies the traditional route. The word you're looking for is "inclusive fitness" and that your DNA actually exists in other people, and if you can cause all the women in the world to have +1 baby, which isn't impossible, if you were to do something outlandish, like double the livable surface area of the world via a behavior, and only allow people with more than 50% of your DNA, but not with the women who didn't, then it will be as if your semen went into all the women in the whole world.
