The difficulty in the case of the newly-married woman is of another type. The discrepancy between the ages at which human beings reach sexual maturity and at which they find themselves capable of maintaining a family, raises a number of exceedingly difficult problems. Seeing that the sexual requirements of man constitute a factor varying very greatly from individual to individual, and to a large extent depending, as is now realized, upon a very complex balance of glandular functions, it is more difficult than most popular moralists seem to realize to lay down general rules applicable impartially to every body. Questions such as the following are raised: Can it reasonably be expected of _every_ man to live ten or more years of his sexually adult life in complete continence? If not, is it better for him to marry young and probably unequipped to support children, having remained continent till that time, or to marry later, probably better equipped financially to become a father, yet having had promiscuous experience of women before marriage? And if he does marry young, can he be expected to remain continent in his married life till he and his wife feel that they can satisfactorily maintain a family? If he finds he cannot do this, should he proceed to have children whom he cannot properly support, or is it better for the couple to overcome their dislike of contraceptives――a feeling which it is idle for advocates of Birth Control to ignore――and thus avoid having children till they are wanted? These are a few of the general questions which are raised in this connexion to which no comprehensive answer can possibly be given.
