The Eiffel Tower (Sex Position) is a position that involves two men and one female. One male will typically penetrate her vaginally – but may engage in anal sex dependent upon the female’s preference, while another male will receive fallatio from the female who is in the doggy style position.
In addition to this the men join hand over top the female and thus resemble the base of the Eiffel Tower with the tower’s legs converging into one structure. For this reason one could consider this position a funny sex position due to the nature that the males hold hands, which is not typical in a double penetration of a female.
Three women, or two women and one male with the addition of a strap-on harness or two could hypothetically complete this Eiffel Tower position, however the odds of this position being planned for are very low, as is the knowledge of this position.
