Plumber Position is a sexual position used for fellatio. A penis-haver squats down to present their penis to their partner, who sucks the receiving-partner's penis while resting on their knees and elbows. This sex position gets its name because the performing-partner’s position resembles the position of a plumber getting underneath a sink for repairs. The plumber position has medium-level difficulty.

While the plumber position does not leave a lot of accessibility to include sex toys, it is still possible. For example in the image below, the performing-parter is using the Satisfyer Love Beads while performing fellatio, which allows for both partners to receive stimulation at the same time. The receiving partner can also use an anal toy during this position, if they want to.
