At one point in the play Othello, protagonist Iago reveals (untruthfully) to the title character that, when he once shared a bed with Cassio the latter embraced him, apparently caught in the throes of a dream and imagining his bedmate to be Desdemona; Iago's construction of this untruth may call into question Iago's sexual orientation, especially if one considers his bitter relationship with his wife (in a later soliloquy, it is revealed that he suspects her of infidelity with both Othello and Cassio). This invites the theory that Iago acts out of repressed desire for Othello, which goes further towards explaining his desire to destroy Desdemona - who has attained the moor's affections - simultaneously.
