(previews start on Saturday; opens on July 22) In Yussuf El Guindi's drama, starring Alia Attaliah, Quinn Franzen and Karan Oberoi, an Arab-American couple attempt to improve their troubled marriage with mutual sexual adventure. (Has this ever worked for anyone?) Though erotic experiments soon give way to a less amatory exploration of identity politics. 59E59 Theaters presents the Portland Stage production.
