I notice a not uninteresting parallel here. Whereas, for most people, the word ‘mental’ means ‘conscious,’ we found ourselves obliged to widen the application of the term ‘mental’ to include a part of the mind that is not conscious. In a precisely similar way, most people declare ‘sexual’ identical with ‘pertaining to reproduction’—or, if you like it expressed more concisely, with ‘genital’; whereas we cannot avoid admitting things as ‘sexual’ that are not ‘genital’ and have nothing to do with reproduction. It is only a formal analogy, but it is not without deeper significance. However, if the existence of sexual perversions is such a forcible argument on this point, why has it not long ago done its work and settled the question? I really am unable to say. It seems to me that the sexual perversions have come under a very special ban, which insinuates itself into the theory, and interferes even with scientific judgement on the subject. It seems as if no one could forget, not merely that they are detestable, but that they are also something monstrous and terrifying; as if they exerted a seductive influence; as if at bottom a secret envy of those who enjoy them had to be strangled—the same sort of feeling that is confessed by the count who sits in judgement in the famous parody of _Tannhäuser_: So in the Mount of Venus conscience, duty, are forgot! —Remarkable that such a thing has never been my lot! In reality, perverts are more likely to be poor devils who have to pay most bitterly for the satisfactions they manage to procure with such difficulty. That which makes perverse activities so unmistakably sexual, in spite of all that seems unnatural in their objects or their aims, is the fact that in perverse satisfaction the act still terminates usually in a complete orgasm with evacuation of the genital product. This is of course only the consequence of adult development in the persons concerned; in children, orgasm and genital excretion are not very well possible; as substitutes they have approximations to them which are again not recognized definitely as sexual.
