Sex should be a perfect balance of pain and pleasure. Without that symmetry, sex becomes a routine rather than an indulgence.

Lust's passion will be served; it demands, it militates, it tyrannizes.

No kind of sensation is keener and more active than that of pain its impressions are unmistakable.

Hope is the most sensitive part of a poor wretch's soul; whoever raises it only to torment him is behaving like the executioners in Hell who, they say, incessantly renew old wounds and concentrate their attention on that area of it that is already lacerated.

Variety, multiplicity are the two most powerful vehicles of lust.

Crime is the soul of lust. What would pleasure be if it were not accompanied by crime? It is not the object of debauchery that excites us, rather the idea of evil.

It is always by way of pain one arrives at pleasure.
