being peculiar, was a most common one, and I was quickly initiated into all the mysteries of inversion, with its freemasonry and ‘argot.’  Altogether my experience of inverts has been a pretty wide and varied one, and I have always endeavored to classify and compare cases which have come under my notice with a view to arriving at some sort of conclusion or explanation.

“I suppose it is due to female versatility or impressibility that it is possible for me to experience mentally the emotions attributable to either sex, according to the age and temperament of my companion; for instance, with one older than myself, possessing well-marked male characteristics, I am able to feel all that surrender and dependence which is so essentially feminine.  On the other hand, if with a youth of feminine type and behavior I can realize, with an equal amount of pleasure, the tender, yet dominant, attitude of the male.

“I experience no particular ‘horror’ of women sexually.  I should imagine that my feeling toward them resembles very much what normal people feel with regard to others of their own sex.”  M.N. remarks that he cannot whistle, and that his favorite color is green.

In this case the subject easily found a moral modus vivendi with his inverted instinct, and he takes its gratification for granted.  In the following case, which, I believe, is typical of a large group, the subject has never yielded to his inverted impulses, and, except so far as masturbation is concerned, has preserved strict chastity.
