Alexandra Katehakis said this quote

Spiritualizing sex is actually a movement of energy—feeling and emotion—that rises within you and moves into your sexual physicality as an alive, tender, erotic, or passionate expression. Your bodies move without inhibition so all the energy can flow out of you and between the two of you. You allow spiritual energy to express its dance through you. Sexuality can be a profound demonstration of your love, and especially your freedom, to express and bond. Spiritual sex, then, combines how you express your love with the intentions or blessings you bring to your partnership.
