I wanted to say when I was in the middle of her breasts that it's strange.
And simple ocho cortado is very awkard.
Dancing her in front of her gives you a better feel where she is,
and your frame is not shifted to the side i.e. shoulder for giro.
And all body dissociation you make it will be well transfered and all body movements as well.
And you push her with your body, arms are only for the embrace and rotation that are led with frame and opening shoulder.
Arms shouldn't be stiff not limp, but active.
Varying embrace in CE you prepare partner for various circular movements.
e.g. using free leg, circular colgada, dinamic circular movements.
So remember: embrace is never constant during the dance.
Dancing that try to be in V position, you slightly to your left, her to her right.
Here forehead should be on your cheek.
So you will be able to feel her like you would have and instrument that you play e.g. violin.
The way she steps, the weight, where is her free leg cause all spine movements will be transfered.
Check Pablo Rodriguez and Noelia Hurtado.

If you are taught by Julio Balmaceda teachers that you have stiff embrace, but very flexible lower part.
