I looked in the dictionary for "heteral". There are two words that are close.
Hederal : of or pertaining to ivy.
I am not sure if this is talking about a very entwined position, or about sex with plants. I am personally in favor of the former. The latter doesn't exite me, but to each his own.
Hetaera: An ancient Greek courtesan or concubine, especially one of a special class of cultivated female companions.
Mmmm... cultivated female companions sounds interesting. This sounds too good to not be illegal
