I don't agree that expression by ballet port de bras is inherently feminine or masculine, but perhaps that's not what you meant. I think guys can be just as uniquely expressive as women, and the tools given to them are neutral.
One of my favorite mime passages is in the Royal Ballet's video of the Nutcracker with Alina Cojocaru and Ivan Putrov, where the Nutcracker is describing the rat battle to the Sugar Plum Fairy. I think this sequence shows a very male perspective on the expressiveness of port de bras.
Forgive me Andre Yew, but gesture, which is a part of mime, is not the same as port de bras in my understanding of the term as used in academic classical ballet.
