In the contact improvisation scene most people don't have that. Male to male physical intimacy is perfectly fine in that scene. There you have people who value authentic expression instead of playing out roles.

Authentic expression, or just different roles? I'm fairly sure that if I was involved in contact improvisation, it would be the latter for me. That is, these are the customs I see here, so while I am here, I will adopt these customs.

It seems to me that authentic expression is not in opposition to roles, but is orthogonal to them, just as in speech, truthfulness is orthogonal to the language being spoken.
