Hitler presented himself publicly as a man without a domestic life, dedicated entirely to his political mission. However, he had a fiancée in the 1920s, Mimi Reiter, and later had a mistress, Eva Braun. He had a close bond with his half-niece Geli Raubal, which some commentators have claimed was sexual, though there is no evidence that proves this. All three women attempted suicide (two succeeded), a fact that has led to speculation that Hitler may have had sexual fetishes, such as urolagnia (aroused by urine or urination), as was claimed by Otto Strasser, a political opponent of Hitler. Reiter, the only one to survive the Nazi regime, denied this.Some theorists have claimed that Hitler had a relationship with British fascist Unity Mitford.
