From: Autobiography of an Androgyne 1918, NEW YORK, THE MEDICO-LEGAL JOURNAL. The author went by different names, Ralph Werther/Jennie June/Earl Lind.

Up to my early thirties, I yearned to be called “Baby” by decidedly virile males, and to have them treat me as a baby and a weakling. All through my open career as a fairie, I conducted myself with intimates in the same way as a baby of two years towards its mother. Whenever I have seen an infant nursing, I have been seized with a desire for fellatio cum viro of about my own age, and have sometimes even experienced an attack of babyish actions, as panting or cooing in satisfaction, or swayed the head or other parts of the body, a sort of natural graceful dance of these parts.

To mimic the baby and the woman in his presence was a rare pleasure. Up to my early thirties, in all my conduct with him, I was more feminine than any woman and as babyish as a three-year old. Sexually I have never grown out of babyhood.

I liked to be regarded as the slave. In the “Enslaving Ceremony,” I lay prostrate on the floor, my companion towered above, placed his foot on my head, and pronounced me his slave. I have always felt that a woman should adore her husband so much as to delight in being treated as a slave, and to suffer gladly any abuse by her lord. In the “Ceremony of Adoration,” my companion stood upright, I prostrated myself, clasped his legs, pressed my lips against his feet, recited all the heroic qualities which enslaved me to him, and cried out over and over again my love and adoration for him. Associates have said they only hoped they would ultimately secure a wife who would adore them as I.

It has been noted by others that TIMs frequently express an obsession with being "petted". I had thought that it might stem from fixating on and identifying as anime catgirls, but this account from 1918 is equally obsessed.

I long to be made the pet of my classmates. Would it be unbecoming to show my girlishness to them occasionally, and welcome and encourage their caresses which I sometimes receive?

But he called out angrily: “Who are you looking at?” “Pardon me for my rudeness, but I was wishing I could get acquainted with you. I am a baby, and I want a big, strong, brave fellow like you to pet me. I’ll give you a dollar if you’ll pet me for a few minutes, and let me sit on your lap.”

The “gang” received me kindly, petted and soothed me as one would a peevish baby, which I resembled in my actions, fretting and sobbing in happiness as I rested my head against their bodies.

The young men petted and babied me more than they did any of the girls...

...as “Jennie June” I have impersonated a baby girl before a hundred soldiers at a time without being in the least embarrassed. I would fret after the manner of a baby and sob just for the pleasure of having them soothe and pet me.

I was madly attracted toward all three, and now reclining in the bosom of one, and now in that of another, I gave utterance to the infant’s natural language expressive of contentment at being petted and babied by these giants, whom I affectionately called my “Big Braves.”

I was then called upon to say good-by—as I feared, forever—to my much coveted position of pet of a fort,

I longed to be where I am regarded as a girl and a baby, and where I am flirted with and petted....
