Stop calling me a man!

[David Bailey]

I agree with this. In fact, the more I dance the less I find the actual act of sex "sexual"

That definitely falls into the "TMI" category.

I think this is correct. But I'm sticking to my guns that men should not line up as women because an embrace from a strange man might cause offence to other men and it's not what men signed up for. Rumours that you "have to dance with other guys at Andy's classes" might also cause me to lose income and that's much more important.

Have you considered occasional reverse-roles for the entire class? I do this all the time at the start of my classes. That removes the "social problem" of the occasional male follow / female lead, simply because everyone's doing it.
