What is Othello requesting in his final speech in Act 5?

Othello has always been concerned with his reputation and public image; this was one of his justifications for killing Desdemona. His last speech reveals that he is still fixated on this cause; "speak of me as I am," he tells them, yet there is great irony in this statement, since he goes on to misrepresent himself and his motives. He says that he is "not easily jealous," although it is apparent from Iago's first insinuations that he is very jealous and possessive of his wife. He also says he is one who "drops tears as fast as the Arabian trees their med'cinable gum"; however, Othello found it difficult to be sorry for killing his wife, until he found out that his motives were wrong (V.ii.341-350).
