Rh The hetero-sexual instinct may be but rudimentary, manifesting itself simply in unconscious (dream) life; or (episodically, at least) it may be powerfully exhibited.

The sexual instinct toward the opposite sex may be strengthened by the exercise of will and self-control; by moral treatment, and possibly by hypnotic suggestion; by improvement of the constitution and the removal of neuroses (neurasthenia); but especially by abstinence from masturbation. However, there is always the danger that homo-sexual feelings, in that they are the most powerful, may become permanent, and lead to enduring and exclusive contrary sexual instinct. This is especially to be feared as a result of the influences of masturbation (just as in acquired inversion of the sexual instinct) and its neurasthenia and consequent exacerbations; and, further, it is to be found as a consequence of unfavorable experiences in sexual intercourse with persons of the opposite sex (defective feeling of pleasure in coitus, failure in coitus on account of weakness of erection and premature ejaculation, infection). On the other hand, it is possible that esthetic and ethical sympathy with persons of the opposite sex may favor the development of hetero-sexual desires. Thus it happens that the individual, according to the predominance of favorable or unfavorable influences, experiences now hetero-sexual, now homo-sexual, feeling.

It seems to me probable that such hermaphrodites from constitutional taint are not infrequent. Since they attract very little attention socially, and since such secrets of married life are only exceptionally brought to the knowledge of the physician, it is at once apparent why this interesting and practically important transitional group to the group of absolute contrary sexuality, has thus far escaped scientific investigation. Many cases of frigiditas uxoris and mariti may possibly depend upon this anomaly. Sexual intercourse with the opposite sex is, in itself, possible. At any rate, in cases of this degree, no horror sexus alterius exists. Here is a fertile field for the application
