So to a married man, Solomon gives this exhortation: “Drink water out of your own cistern, and tricklings out of the midst of your own well.

Proverbs 5:15-17.

“Your own cistern” and “your own well” are poetic expressions for a beloved wife. Experiencing sexual enjoyment with her is likened to drinking refreshing water. Unlike the water supply in public places, a cistern or a well is considered private property.
