So, disclaimer, your YMMV, but having run both Khan and EmpD, here is how I would differentiate the two in terms of pure sexual activity.
On Khan, I felt like a caveman, completely primal in my approach and demeanor. I had written about it in detail in one of the Khan threads which I think you saw recently.
EmpD takes a few cycles to heat up, so it won’t be as immediate as Khan, though, to be fair, my particular posting in that Khan thread was when I was on Khan Stage 3 so I was on my third cycle of Khan at that point also, having run stages 1 and 2 for a cycle each.
On EmpD I feel like a lion that’s playing with it’s food before suddenly devouring it. Without getting too detailed, there is from women I have been intimate with, a mix of anticipation and even something bordering on a slight fear of the unknown, only because of the amount of control that I have when it comes to how everything unfolds. I can’t quite explain it. And at some point, playtime is over and it’s time to feast.
It is a markedly different experience than Khan, still very dominant and super sexually charged. Just a very different execution path.
Put simply, when you’re the King, you don’t need to dominate, you just are.
