It gives the Witch a sense of freedom and greater ability to project energy without the restriction of clothes. The simple answer is no, but an explanation of this requires an understanding of the difference between Wicca and Christianity. The Devil is a Christian concept, essentially invented to explain the paradox of the existence of evil in a world supposedly created by a single all powerful benevolent God. Often people were effectively forced to change their religion and pay homage and money to the church. As Wiccans do not believe in a single all powerful God they do not have any need, nor believe in the devil.

Sex is precious and regarded as sacred to witches, certainly not something to be abused. It is the ultimate union of love between a man and woman, and is a blessing from the Goddess and God. It is an expression that can only be experience by a married or established couple in private, and never to be used in a circle with other members of the group as it would ruin the trust between members. This positive morality advises against using the power of magic to do anything other than help anyone or anything. The price of braking this rule can be high.
