do what comes naturally.

Philosophy in the Bedroom Ah, Eugenie, have done with virtues! Among the sacrifices that can be made to those counterfeit divinities, is there one worth an instant of the pleasures one tastes is outraging them? Come, my sweet, virtue is but a chimera whose worship consists exclusively in perpetual immolations, in unnumbered rebellions against the temperament's inspirations. Can such impulses be natural? Does nature recommend what offends her? Eugenie, be not the dupe of those women you hear called virtuous. Theirs are not, if you wish, the same passions as ours; but they harken to others and often more contemptible... There is ambition, there pride, there you find self-seeking, and often, again, it is a question of mere constitutional numbness, of torpor; there are beings who have no urges. Are we, I ask, to revere such as them? No; the virtuous woman acts, or is inactive, from pure selfishness. Is it then better, wiser, more just to perform sacrifices to egoism than to one's passions? As for me, I believe the one far worthier than the other, and who heeds but this latter voice is far better advised, no question of it, since it only is the organ of Nature, while the former is simply that of stupidiy and prejudice. One single drop of fuck shed from this member, Eugenie, is more precious to me than the most sublime deeds of a virtue I scorn.
