The spider monkey is an extremely complicated sex position that must be performed by very flexible and strong lovers. This position is not for everyone, and there is a risk of getting injured, especially for the man’s side.
The man stands firmly on his toes, while his feet are spread apart with the same dimension as his shoulders. The woman stands in reverse position, with her head on the bed, and her back to the man’s back leg and her bottom is a bit under the butt of her lover. Her knees are bent, and feet are at the man’s sides.
The man uses his hands to hold the woman’s ankles for support. When he enters, he lets go of one ankle so he can bend his penis downwards and enter the woman’s vagina. And then he returns his hand to her ankle. This position does not allow fast sex.
