Sometimes the development of higher sexual feelings toward the opposite sex suffers, on account of hypochondriacal fear of infection in sexual intercourse; or on account of an actual infection; or they suffer as a result of a faulty education which points out such dangers and exaggerates them. Again (especially in females), fear of the result of coitus (pregnancy), or abhorrence of men, by reason of mental or moral weakness, may direct into perverse channels an instinct that makes itself felt with abnormal intensity. But too early and perverse sexual satisfaction injures not merely the mind, but also the body; inasmuch as it induces neuroses of the sexual apparatus (irritable weakness of the centres governing erection and ejaculation; defective pleasurable feeling in coitus), while, at the same time, it maintains the imagination and libido in continuous excitement.
