the length of the Long march, except for the laoer is too small to reach the touch line.
The point is the long march starts from the cervix, or the bottom of the vagina. No matter how long the laoer is, it cannot enter the cervix. So if the laoer can reach cervix, it is enough for the reproduction purpose. Many techniques exist to improve fertality by making sure the long march can start and starts at the right place.
In fact, if the laoer is too long, it will make the receiver uncomfortable and cause damage to the cervix.
Size matters, but match is even better.
