There are masculine and feminine gifts in intimacy, and each gift comes with its own responsibility.
The direction of growth of a relationship is primarily the man's responsibility.
The energy of an intimacy pleasure, sexual flow, and vitality—is primarily the woman's responsibility.
A simplified way of saying this is that the man is responsible for the
woman's depth of love, or openness of mood, and the woman is responsible
for the man's "erection" or energy in the body.
