Wherever the older morality has decayed, prostitution also has decayed. The young man who would formerly have been driven to occasional visits to prostitutes is now able to enter upon relations with girls of his own kind, relations which are on both sides free, which have a psychological element quite as important as the purely physical, and which involve often a considerable degree of passionate love on both sides. From the point of view of any genuine morality, this is an immense advance upon the older system.
