Haply, for I am black
And have not those soft parts of conversation
That chamberers have.

– William Shakespeare

Othello, Act 3, Scene 3. Othello’s feelings of insecurity about being a black man married to a white woman are evident here. He admits that he doesn’t have the conversational skills of men who are comfortable in the chambers of ladies. He seems to think that the racial differences between Desdemona and himself could cause a rift in their relationship. This self-doubt comes after Iago raises Othello’s suspicions about his wife’s fidelity.
