sx/so vs. sx/sp
Both sexual types have a large energy, and tend to be pretty obtrusive in a social setting. The difference is that sx/so's have a smooth energy that flows outwards, while sx/sp's energy goes in bursts. In general, sx/sp's are more in their heads, thinking.. and will sit just thinking about the conversation, then suddenly feel a big burst of sharing come on, and burst in, sometimes at the wrong point, because they're not as attuned to the social dynamic.
When sx/sp's are in withdrawal mode, they're basically tuned out. This is why they can appear more like a self pres type. (...) If you look at them closely at such times, they'll appear to be elsewhere mentally. If you try talking to them, they'll display a reluctance to be drawn in. However, if something really catches their interest, they'll change dramatically and become like a regular sx/sp, all burst-y and jerky and excited. This is something I don't like about myself, one of my biggest faults that's been brought up by numerous people through the years. It's like I can't always get a feel for where to interject my thoughts in a group conversation, so I wind up blurting, and talking over people from all directions, even when I'm trying to gauge it. Sx/so's are very socially attuned and much smoother, regardless of e-type, than sx/sp's. Unlike the sx/so's smooth outward flow (sometimes likened to a generator), sx/sp energy moves in/out/in/out in unpredictable bursts (sometimes likened to lightening). That's one reason sx/sp's can angry others more than sx/so's.
