In Helen Edmundson's version of Orestes, what point is she trying to make about the sexual relationships?

Just saw it last night. We noticed lots of interesting threads about sexuality, from the ';pimp'; clothing of the grandfather, Helen's taunting of the virgin Electra, Electra's view of Helen as whore, Helen's description of Clytemnestra as a rape victim making the best of a bad marriage by finding a lover, and the flowering of incestuous attraction between Electra and Orestes. I thought it was interesting that right after the scene when Orestes is aroused by his sister, he suddenly switches from accepting death to wanting to live. Fits nicely with a Freudian analysis--the return of Eros banishes Thanatos.In Helen Edmundson's version of Orestes, what point is she trying to make about the sexual relationships?
