Why does Holden allow Maurice to send the prostitute to his room? How does Holden excuse his agreeing to meet a prostitute?

When he arrives back at the hotel, Maurice, the elevator man asks if he would like a prostitute. He tells Holden it will be five dollars for a brief encounter and fifteen dollars for a girl who will stay until noon,  and Holden, depressed and flustered, accepts. He says he would like the five-dollar deal. While waiting in his room, he again thinks about his cowardice, because he feels that his lack of aggression has prevented him from ever sleeping with a woman. Women, Holden believes, want a man who asserts power and control.
