I think it worked well when I was charismatically just entertaining the group of us that were at the event together (some strangers but all connected somehow and at a big event together where we all felt a little shy). And he was VERY quiet. I kept reaching out to him and connecting and then moving on. I mistook the ESI-Se for a SLI or something and was just being extroverted and paying him compliments in a warm, sincere way but also turned back to the group. I think it let him get the idea I wasn't hunting him. When he started stationing himself at my side the next hour and offering to drive me to the next place we all danced and talking to my friends about me, I realized he was introvert version making a gesture/move/asking me out. It made me uneasy because he was so starched (literally), and I misunderstood that's sometimes a XSI thing. I am a swaggery,fly-by-the-seat of my pants person, and I thought he had the wrong idea about us working out. But the buddy telling me he was sleeve-tatted up under the clothes and my friend's exhortation got me to warily agree.
I liked that there was a mutual confidence, freedom/you don't own me, and power-sharing vibe the rest of the time. Kinda seems like we could both be hunty but on the same team...Hunting orgasms together is a good past-time for Ni-Se couples, imo. I want to run at him sometimes, him lurch at me others...kinda like that song..
