[Tango-L] Social-ethical behaviours and protocols

[Ruben Malan]

This question may be superfluous for some, and perhaps controversial for many, but I'm wondering if there is any known written or unwritten code of ethics regarding girlfriends  and boyfriends, fiancés, husbands and wives proper behaviors Not only among themselves but  dancing with other partners also. Are there any traditional unspoken rules at the Buenos Aires Milongas regarding how accompanied women or men should behave with the opposite sex (or same sex) casual partners, without falling in the "questionable" or  "excess" category?  

Is there any observed difference in USA or Europe?
