"As to sexual inversion my personal experience has been confined to two or three _grandes passions_ for boys, the first of which possessed me when between the ages of 16 and 18, and involved, when I was 17, the most intense mental emotion, of a romantic kind, tinged with poignant jealousy and vexation at comparative coldness toward myself. These love passages never led me into indelicate behavior (I was once threatened with such treatment myself by a stranger whose acquaintance I made one day at the British Museum, when a lad of 15. He took me to his bedroom at an inn, locked the door, and showed me a collection of coins, giving me some, and, while doing so, attempted to take indecent liberties; but I pretended that I must catch a certain train, unlocked the door, and made a hasty escape), nor was any gratification sought beyond occasional kisses and other innocent endearments, though such caresses would sometimes excite an erection, which I carefully concealed. These amours were, however, no outcome of perverted instinct, nor were they any bar to fancies for the opposite sex which affected my imagination rather than my heart."
