Sadly, I hesitate to invite women I don't know and haven't watched dancing. I have to hesitate: at worst I've had attempts at a close-ish embrace (even without actual body contact) repulsed, as if I were an unwelcome pest; at best there's merely a sense of condescending boredom at my lack of wild stage moves. So if I do invite a woman I don't know and haven't seen dancing, and it turns out that she not only follows close embrace but obviously enjoys it... what a bonus!
I met her again recently as I was leaving a rather dark milonga, lit only by coloured flood-lights: I hadn't noticed her inside. She was fuming about the pathetic wannabe stage-performer attempts of dancers. I had to ask where she herself had learned to dance... but the answer was pretty obvious by now. 'In the Buenos Aires milongas, sometimes the leaders just walk! Don't people here realise what a pleasure it can be just to walk? & they turn so smoothly...' Nostalgia upon nostalgia!
At least there are dancers in London who are sympathetic. London doesn't exactly have a name for excellence in tango, but good salon dancing is beginning to be welcomed, and 'specialist' milongas, like the salon room at '33' on Sunday night, are becoming popular. I can only hope that more people will start to realise how good considerate, elegant and musical dancing can be.
