Havelock Ellis (February 2, 1859 - July 8, 1939) was a British sex researcher. His thoughts on sexuality are expressed in an excerpt from Studies in the Psychology of Sex: Volume 1:
Suppose that eating and drinking was never spoken of openly, save in veiled or poetic language, and that no one ever ate food publicly, because it was considered immoral and immodest to reveal the mysteries of this natural function. We know what would occur. A considerable proportion of the community, more especially the more youthful members, possessed by an instinctive and legitimate curiosity, would concentrate their thoughts on the subject. They would have so many problems to puzzle over: How often ought I to eat? What ought I to eat? Is it wrong to eat fruit, which I like? Ought I to eat grass, which I don't like? Instinct notwithstanding, we may be quite sure that only a small minority would succeed in eating reasonably and wholesomely.
The sexual secrecy of life is even more disastrous than such a nutritive secrecy would be; partly because we expend such a wealth of moral energy in directing or misdirecting it, partly because the sexual impulse normally develops at the same time as the intellectual impulse, not in the early years of life, when wholesome instinctive habits might be formed. And there is always some ignorant and foolish friend who is prepared still further to muddle things: Eat a meal every other day! Eat twelve meals a day! Never eat fruit! Always eat grass! The advice emphatically given in sexual matters is usually not less absurd than this. When, however, the matter is fully open, the problems of food are not indeed wholly solved, but everyone is enabled by the experience of his fellows to reach some sort of situation suited to his own case. And when the rigid secrecy is once swept away a sane and natural reticence becomes for the first time possible.
