a girl yourself and can understand why she is shocked.
When she is about to walk away, you tell her
you have no penis, that you don't
know what got into you.  You get on your knees.
She suddenly bends down to kiss your shoulder and you know
you're on the right track.  You tell her you want
to bear children and that is why you seem confused.
You wrinkle your brow and curse the day you were born.
She tries to calm you, but you lose control.
You reach for her panties and beg forgiveness as you do.
She squirms and you howl like a wolf.  Your craving
seems monumental.  You know you will have her.
Taken by storm, she is the girl you will marry.
This monumental craving is important either because the marriage factor of this line references to the act of making love (the connection that he feels to the girl).  Or the  marriage factor of this line could refer to the way he could have fallen in love with the girl as he fulfilled his animalistic craving.
