Hitler's sex life has long been the subject of speculation and rumours, many of which were invented or spiced up by his political enemies.^[7] While the sexual preferences of many members of Hitler's inner circle are known, conclusive evidence of Hitler's sexuality is lacking. The evidence that exists about Hitler's private life is largely from people in his inner circle, such as his adjutants, his secretaries, Albert Speer, the Wagner family, and others. There is evidence that he had infatuations with several women, as well as evidence of his antipathy to homosexuality, and no evidence that he engaged in homosexual behaviour.^[8][9][10] Kershaw describes him as being repelled by personal contact and sexual activity, including homosexuality and prostitution, especially as a young man in Vienna. He was afraid of contracting a sexually transmitted infection.^[11]
