Montesquieu

“ She is marrying jealously personified, a husband who is no husband; who will only exchange his coldness for an impotent despair; who, by perpetually recalling the memory of what he was, will but remind her of what he no longer is; who, always ready to possess, but never possessing, will for ever deceive himself and her, keeping constantly alive to the wretchedness of her condition.
And then! to be always in dreams and fancies; to live only in imagination; to be always on the threshold, and never in the abode, of pleasure ”

“ I have heard you say a thousand times that eunuchs do enjoy a certain pleasure with women, which we know nothing of; that nature compensates them for their loss, having means with which to amend their unfortunate condition; that one may cease to be a man, but not to feel desire; and that in that state one acquires a third sense, and exchanges, as it were, one pleasure for another. ”
