Always there seems to be a conflict between sex and spirituality.
But what is it that causes an erection but blood from the heart.
Sex is the consummation of love.
The heart's desire : the desire for union with another (the beloved).
It has been said that to be loved is pleasurable but to love is more pleasurable still.
The aim is not to eat up love like a black hole but to give love like a star.
Of course no one can give day and night without ceasing, there will always be giving and receiving = mutuality.
But love is the key.
The heart mediates between the body/mind and the spirit.
Love will grant you your heart's desire : the consummation of love which is union with the beloved = sex.
