The conjugal sex is really unitive when the three dimensions of the unity are. These dimensions are linked to the human nature, what means the constitutive elements of the human beings: body, soul and heart with all corollaries. The physical and carnal union, per se, the physical joys of the union of bodies, the sensible and spiritual joys of the union of bodies, the affective joys of the union of bodies are signs of this unitive aspect.

Each one should be an active agent and a passive agent. *The donation and the reception of persons (body, soul and heart) for the conjugal union, not for the conjugal fusion (merger).
