Love and lust are not the same, and as lust is defined here it is restricted to sexual lust, which is not the only kind of lust, since there are many things capable of giving a person intense pleasure, though most physical ones seem to be related with sex or food for most men and women, both of which seem to have an innate biological ground.

In so far as sexual lust and associated feelings are concerned: It seems fair and realistic to assume that most of the mutual interest between the sexes is more moved by sex or hormones than by love. Even so, all human emotions except in extreme situations are mixed, and are made up of many tendencies, feelings and needs, as it is also true that other persons can satisfy (or fail to satisfy) many different needs or interests one has.
