concupiscence

Concupiscence (from Late Latin noun concupiscentia, from the Latin verb , from con-, "with", here an intensifier, + cupi(d)-, "desiring" + -escere, a verb-forming suffix denoting beginning of a process or state) is an ardent, usually sensual, longing. In Catholic theology, concupiscence is seen as a desire of the lower appetite contrary to reason. For Christians, concupiscence is what they understand as the orientation, inclination or innate tendency of human beings to long for fleshly appetites, often associated with a desire to do things which are proscribed.
