Association with prostitutes, if it becomes at all habitual, is likely to have a bad psychological effect upon a man. He will get into the habit of feeling that it is not necessary to please in order to have sexual intercourse. He will also, if he respects the usual moral code, tend to feel contempt for any woman with whom he has intercourse. The reaction of this state of mind upon marriage may be extraordinarily unfortunate, both where it takes the form of assimilating marriage to prostitution, and where it takes the opposite form of differentiating it as widely as possible.
