The way to woo a Pisces is to make sure that he or she knows that you are playing for keeps. This is the sign of soulmates and like penguins, Pisces natives like to mate for life. Loyalty is very important to this sign so make sure you make your intentions clear from the beginning. They like to be courted, slowly, formally and with great sincerity.
They will not tolerate being less than number one in your life and from the point at which your relationship begins with one you will not be able to make another decision in your life ever again without consulting him or her.
