That which we call the ‘missionary position’ is, in Teleleli, known as The Congress of Serpents.
It is rumoured that some wizards who are well-versed in the ways of the extra dimensions Yafir and Yiraf have invented a series of non-Euclidian sexual positions.
There is a type of robot which can both disassemble itself, and have sexual intercourse. As such, they have invented sexual positions with no equivalent among biological creatures. It is not known why they were so designed. It was not to serve as concubines to creatures of flesh, since they utterly refuse to do so. Nor do they reproduce in this fashion. Some speculate that they are intended to drive humans and similar beings mad with envy.
