Robert Graves  and Sacheverell Sitwell  (who also personally knew him) stated that Owen was homosexual , and homoeroticism is a central element in much of Owen's poetry.     Through Sassoon, Owen was introduced to a sophisticated homosexual literary circle which included Oscar Wilde 's friend Robbie Ross , writer and poet Osbert Sitwell , and Scottish writer C. K. Scott Moncrieff , the translator of Marcel Proust . This contact broadened Owen's outlook, and increased his confidence in incorporating homoerotic elements into his work.   Historians have debated whether Owen had an affair with Scott Moncrieff in May 1918; he had dedicated various works to a "Mr .",  but Owen never responded.
