This describes my ISFP wife. Compare this 9 Sx description with that of the "Mystic" in the OP chart. It doesn't even match up.
The energy of the sexual instinct is at odds with the dominant type Nine energy and makes for a conflicted subtype. These Nines can appear to have a stronger connection to Three, for this reason. The assertive fiery energy engages in a constant push-pull with the calm peace-seeking energy of the Nine. This subtype can have an intense relationship with their environment. They are often drawn to solo sports or to an active engagement with nature that involves some risk and exertion. These Nines are drawn to peak experiences. They might enjoy outdoor solo sports or engaging in nature by way of hiking, rock climbing etc.
With the social instinct last in the stacking, there can be an on/off quality when it comes to relating and these Nines are often somewhat moodier than the other subtypes. As with the self-pres/sexual, this subtype might not engage socially with the same smoothness as other subtypes of Nine. They seem to go towards others in a staccato fashion – they connect in bursts, then withdraw.
When it comes to intimate relationships, this subtype can be needy. The merging of the Nine combines with the intensity of the sexual instinct to create a subtype that will always be in danger of losing themselves in a relationship. Their boundaries for themselves and their partner can become blurred which can lead to conflicts. This subtype might have a hard time judging clearly the degree to which they have merged.
