You will have a war of the sperm inside you!
Either man has the chance of impregnating the woman. If she releases two eggs, either one or both of them could impregnate her.
Its like a race or chance only one sperm will fertilize the egg,except you release two eggs but the sperm will still be from either one of the men.
If the mens like do what is the results
Only one will make it or you could have twins and one child will be one mans and the other baby will be the others (but thats rare).
