One partner engages in sexual activity while the other stands and dips their triceps on the bench. This position is called the Big Dipper. You might say it's a kind of sex-ercise because of how physically demanding it is. Others think it's just a one-time thing that couples will probably never do again.
There is a strong relationship between the Big Dipper and the Little Dipper sex positions, which are basically the opposite of each other.
An very strong core and arm endurance are necessary for the "dipper" to execute the Big Dipper correctly. This is why the dipper is typically a male. He takes a seat between two solid pieces of furniture, such a sofa and an ottoman. As if doing tricep bench dips at the gym, he sets his hands on the surface behind him and his legs on the piece of furniture in front.
Standing slightly bent over their lover, the Dipper's partner straddles his or her legs. A little stooping may be required if one partner is overly towering. As a means of achieving sexual intercourse, the dipper lowers himself before pushing himself up.
A companion may do squats to help the Dipper out if he has trouble doing full dips. Since maintaining one's endurance while squatting might be challenging, this action can also be used to lengthen the duration of intercourse. On the other hand, the Dipper could discover that it's more comfortable to raise his hips while keeping his arms straight or resting on his elbows.
If the Dipper wants to keep his knees from getting hurt on the Big Dipper, he should bend them slightly.
