From an animist point of view, all material being is imbued with spirit.
Spirit, or the nonmaterial aspect of all things, includes intelligence, emotion, creativity and soul, soul being the sacred life force. Like all that exists, then, humans are material beings imbued with spirit. We are both body and soul, and as an expression of soul, our flesh-and-blood bodies are sacred. Our body’s natural acts are sacred. Sex is sacred.
From a polytheistic point of view, our Creator made our human bodies on purpose, whether through evolution or by other mysterious means, and what the Creator has made is good. He made our genitals on purpose. He gave us the sexual act on purpose. We understand these things as gifts from our Creator.
From an ordinary, scientific-rational point of view, we find that sex enables humans to easily and pleasantly procreate as well as offering us pleasure, comfort, fun, adventure, improved health and other marvelous benefits.
Finally, Polytheistic Animism supports a social structure based on kinship and a morality of loving kindness.
Putting this all together, Polytheistic Animism views sex as sacred, good, useful and righteous. Moral sex is loving and kind, not violent or hurtful, and within this moral limitation, many expressions of human sexuality are acceptable.
