many followers
want to change it for themselves largely because they aren't comfortable
with or have never learned the following the chest with their chest embrace..
I have the opposite perspective. ie: Leaders that haven't learned to make proper contact.
I learned "milonguero" CE first and have no trouble at all following it. However, I open the embrace sometimes with a leader who is trying to dance CE but can't make a good enough connection for me to feel his lead in my body. This is probably most common when the guy collapses his chest and has his shoulders and head more projected than his ribcage. I can only project mine so far into his concave shape!
I doubt this is what is happening to you, but sometimes when the follower opens the embrace with a leader, its not because she doesn't know what she's doing.. its because the leader isn't doing what she needs.
