Either. However , experience shows it is the fertility of the woman that counts. Gallons of sperm won't impregnate a woman who is not fertile. Sometimes , only one bull is available. Sometimes, a particular bull wants a selected woman to breed. Usually , breeding parties are for the woman anyway. Something about a whole group of studs dumping sperm into her pussy to impregnate her is a huge , very profound, sexual mind trip.So do you think it would be better to have a single bull ejaculate inside of you multiple time or to have several bulls all ejaculate inside of you once? What do you think has the better chance of success?
