I have a question concerning Enneagram subtypes/instincts. Theoretically, the Sx subtype is concerned with intimacy and passion, while the So subtype focuses on the social arena - groups, institutions, social movements, subcultures, etc. So far, so good.
But... Does "intimacy" always mean romantic intimacy? What about developing one-on-one relationships with non-romantic/non-family people, like a close group of friends? Is that a So domain activity, or a Sx one?
