Also the number of infections with seamen is nowadays not as it was before—90% due to the prostitutes. The ratio now is about 50/50 between the prostitutes and the “amatrice.” If in earlier days the seaman suffered much from the offer of female-amatrices in a few ports only of Eastern Europe, we now see that in quite a large part of the free world, free sexual intercourse has so much increased that the seaman really is not any more committed to prostitutes but indeed has a lot of trouble to keep free from the amatrices in the streets and in the neighborhood of the seaman’s homes.[…]One might well say, that we have too much been obsessed by the problem of the prostitute and that the real attention should stay fixed upon the promiscuity of man as well as of woman, prostitutes and amatrices, as promiscuity is the determining factor for demand as well as for supply.

I may not be a nocturne or a masterpiece of nightwork, / but I’m no oily composition, no corroded / weathercock in the hay, / no ancient lamb dressed ewe fashion / (nor yet a death’s head on a mopstick, thank you). / I do not affect the Bouguereau quality. / Neither am I an amatrice of naughtiness / —Gay Dashaleigh, Frank Merriwell, Jack Harkaway, Bunny Stutz Bearcat, Bunny / —Your own hare? Or a wig, Madame?—
