this one lady pressed herself against me like a magnet so our hips were touching, and seemed completely ignorant of the fact that I was squirming and uncomfortable. Every time I tried to move back...she just stayed there and there was no escape!!!
I try hard to be sensitive to what I feel from the woman. It's pretty easy to sense whether she is used to that kind of advanced technique or not. If so, I go for it because it makes for better looking dancing. If I feel her try to keep her distance I respect that because it makes for better (more comfortable) dancing if she isn't struggling to maintain her distance.
Yes, I am aware of the physical issues of being in such close contact, especially when pushing forward in closed position, but I have never regarded it in a sexual way, not even in Tango. It's just dancing to me.
