possessed a peculiar sense denied to other boys, for I had never heard of masturbation till I learnt, not the word indeed, but the thing itself. "My curiosity about the real nature of sexual union in the case of human beings set my intelligence to work at the interesting problem, and by carefully studying certain parts of the Bible, Lemprière's classical and other dictionaries, as well as by persistently watching when I could the amorous proceedings of domestic animals, I learnt enough to make its most prominent features pretty clear before I was 11 years of age. I was then all eagerness to have the opportunity of inspecting at close quarters the genitals of women or young girls, and a stay at the seaside when I was 12 made the latter at least feasible. When the shore was nearly deserted, between 1 and 2 P.M., the daughters of the fisherfolk used to besiege the bathing machines and disport themselves in the water, bathing and paddling in various stages of nudity. I would pretend that my whole attention was being given to the making of miniature tunnels in the sand, while all the time I slyly peeped at what I most desired to see, whether in front or from behind, as the dancing damsels stood upright or stooped till their haunches were higher than their heads. I had already read something somewhere about the _clitoris_, and wanted especially to see it, but indistinct glimpses were all that I could obtain; nor was it until I visited an anatomical museum, which then existed at the top of the Haymarket in London, that I learned, a good many years later, from several life-sized models there displayed, the characteristic features of that part, as well as the abnormal modifications to which it is subject, either congenitally or in consequence of profligate habits. I was 15, I think, when I first came to know that girls can masturbate as well as boys. "Long after I had realized why the terms male and female are so distinguished, my imagination was occupied with the possible postures in which the act of copulation may be accomplished by a man and woman; from Horace, Lucretius, Martial, Aristophanes, and, above all, from Ovid's _Ars Amatoria_ I obtained much, but not always very clear, information while still a schoolboy. This was supplemented later by photographic pictures from Pompeiian brothels and photographs from life, purchased at Florence and gloated over one night, with twice-repeated masturbation, and afterward destroyed in a revulsion of shame.
