This is actually an interesting question. The other day there was a guy who hates my guts, and I am aware so I just ignore him. I talked with others and suddenly he needed to talk to me, which for me did not compute as I would continue ocstracizing had I been him.
But you mention not feeling dominant and not being in control, so the breaking ice is a submissive move? Interesting. I did notice that guy feeling tense and super awkward. Good, I can use this.
By the way I also believe that breaking the ice can be very dominant. Some people shut down because they are feeling shy or timid, you are basically leading them out of that state. So how you come at it is important as well.
To help you by the way. You should work on a stronger core and learn to bear more tension ... as tension is probably what is making you make an involuntary move. Perhaps go through an asshole face in order to learn how to withstand social pressure.
