The big dipper is a sexual position which sees a couple having intercourse while one person stands, and the other performs tricep bench dips. Due to its high degree of physical exertion, it can be thought of as a form of sex-ercise. Others believe it’s a novelty position which is unlikely to become part of a couple’s regular repertoire.
The big dipper is closely related to the little dipper sex position, which is essentially a reversal of the position.
