I'm not sx-dominant (I'm so/sx), but I strongly identify with some sx traits.
A question I have for my sx-dominant friends--do you like the drama? The turmoil? The soaring highs and the bottomless lows? The agony? When I was younger and more unhealthy, I'd nudge myself into situations where I knew I'd get hurt just because I liked the intensity of it all. I stared out the window and pretended my life was a movie; I'd even divide it into chapters. When I went through dark and painful times, I would think things like, "This will make fantastic writing material." The things I wrote were super flowery, tortured, ecstatic, etc.
Here's another thing more curious I have to ask you about. Do you experience deep, visceral connections to people? I don't mean in a sexual sense. I mean this rush that you feel--physically feel--around somebody, in a platonic way? Like being so deeply attracted to somebody that you can physically feel a rush through you when you think of them or see them. Caring so deeply for someone, like a friend, that it becomes more than a friendship, but not romantic? Like a special friend. A true, one friend. I don't know. I tried to explaining this concept to my friends who are both sx last, and they had absolutely no idea what I was talking about. My sister, however, who is either sp/sx or sx/sp, understood what I was talking about one hundred percent.
Are these things related to Enneagram? What are your experiences? Do tell.
