"Carlum Carmichael ... believes that Jesus was speaking of himself as the Samaritan woman’s final man when he said ‘you have had five husbands and the one you have now is not your husband!’ Carmichael’s argument goes that Jesus was differentiating between the woman’s previous relationships and theirs, reinforcing that this relationship was not sexual.” (from mothergodexperiment) 

A friend has alerted me to the possibility that the five marriages of the Samaritan woman are not regular marriages, but rather sacred ritual marriages of hieros gamos at a temple in which a priestess and a male member of the community are joined in remembrance of the Goddess (Bride) and her “king” (Bridegroom). The “woman at the well” might be such a priestess and because of her religious role, a leader of her community. But while she is ritually a Bride and per John, Jesus is a Bridegroom, nevertheless, never the twain shall meet, not sexually anyway.

Think about the historical context for your sermon.
