Wiccan sexual mores are primarily guided by two principles: "An it harm none, do what ye will" (The Wiccan Rede) and "All acts of Love and Pleasure are My rituals" (from The Charge of the Goddess by Doreen Valiente).

The first implies openness and honesty with partners. The second implies that all forms of consensual sexuality are blessed.
