On one hand the eternal attraction of man towards femininity (cf. Gn. 2:23) frees in him-or perhaps it should free-a gamut of spiritual-corporal desires of an especially personal and "sharing" nature (cf. analysis of the "beginning"), to which a proportionate pyramid of values corresponds. On the other hand, "lust" limits this gamut, obscuring the pyramid of values that marks the perennial attraction of male and female.
