Would you call this a basic quad? see attached diagram. It's when there are two males and two females. The males have been sexual with the females, but the females haven't been sexual with one another and neither have the males been sexual with one another. It just seems like your basic heterosexual quad to me....but just wondering.
On the diagram, the green means "yes" and the red means "no" as far as direct sexual contact.
The key to life is in being fully engaged and peacefully detached simultaneously and authentically in each moment.
