Oh My Aching Head

Bisexuality at it's best is demonstrated in Max Eastman's Great Companions.  He tells a priceless story about the gutsy Edna St. Vincent Millay.  While at a cocktail party while chatting with a psychologist she complained of recurrent headaches.  The psychologist asked her if she had ever considered that she might -  unconsciously, of course -  have an occasional impulse toward a person of her own sex.  She responded, "Oh, you mean I'm homosexual! Of course I am, and heterosexual, too, but what's that got to do with my headache?"
