text_A: Vaughan Williams's recollections throw some light on Ravel's private life, about which the latter's reserved and secretive personality has led to much speculation. Vaughan Williams, Rosenthal and Marguerite Long have all recorded that Ravel frequented brothels; Long attributed this to his self-consciousness about his diminutive stature, and consequent shortage of confidence with women. By other accounts, none of them first-hand, Ravel was in love with Misia Edwards, or wanted to marry the violinist Hélène Jourdan-Morhange. Rosenthal records and discounts contemporary speculation that Ravel, a lifelong bachelor, may have been homosexual. Such speculation recurred in a 2000 life of Ravel by Benjamin Ivry; subsequent studies have concluded that Ravel's sexuality and personal life remain a mystery.
text_B: If Ravel saw a woman he liked at a party, is there a good chance he would have talked to her?
NO.
