One tanguera told me she didn't like dancing with women because the female lead is generally not strong. There's also the issue of big boobs - which can make it uncomfortable. Of course if you dance like the women in the old French postcard on the left it wouldn't be a problem!
I have danced with women but would never choose to dance with a woman over a man - and I am sure many feel the same. Your thoughts please...
P.S. If you are a man looking to learn tango then we need YOU!! Check out the Tango Teachers Network on TangoAustralia for a school near you - or email me with a request for Tango schools near where you live and I'll let you know what I know about schools in your vicinity.
