That well is the sexual force. The Samaritan woman is your physicality. She is a woman who is looking for the knowledge in this physical world but doesn't know how to start.

Thank you for your response, I would like to clarify; You have said that "The Samaritan woman is your physicality"

Is that because Malkuth or this physical universe, matter, is feminine?

Yes. Malkuth is considered a feminine Sephirah. Remember that when Adam and Eve ate the forbidden fruit (through fornication), Malkuth, the Kingdom, emerged from Yesod and fell, influenced by the lower worlds of Kabbalah.

It is also interesting to note that any Sephirah beneath another is considered feminine in relation to the one above it. This is due to the fact that the lower Sephiroth receive, like a fountain, the effluvia or forces from the worlds above. Since Malkuth is the bottom of the Tree of Life, it is therefore definitively feminine.
