It may further be remarked that the anus, which is the more aesthetically unattractive of the excretory centres, is comparatively remote from the sexual centre, and that, as R.
Hellmann remarked many years ago in discussing this question (_Ueber Geschlechtsfreiheit_, p.

82): "In the first place, freshly voided urine has nothing specially unpleasant about it, and in the second place, even if it had, we might reflect that a rosy mouth by no means loses its charm merely because it fails to invite a kiss at the moment when its possessor is vomiting." A clergyman writes suggesting that we may go further and find a positive advantage in this proximity: "I am glad that you do not agree with the man who considered that Nature had bungled by using the genitals for urinary purposes; apart from teleological or theological grounds I could not follow that line of reasoning.
I think there is no need for disgust concerning the urinary organs, though I feel that the anus can never be attractive to the normal mind; but the anus is quite separate from the genitals.

I would suggest that the proximity serves a good end in making the organs more or less secret except at times of sexual emotion or to those in love.

The result is some degree of repulsion at ordinary times and a strong attraction at times of sexual activity.

Hence, the ordinary guarding of the parts, from fear of creating disgust, greatly increases their attractiveness at other times when sexual emotion is paramount.
