I've heard a lot of Wiccans/Pagans/Witches say that sex magick isn't a valid form of magick, or that those who practice it are perverted. This is not true. It's easy to say these things when one is afraid of them or has grown up with a certain code of morality. Sex magick is very powerful and generates significant amounts of energy that can then be directed towards your spell or ritual intention. It's not for everyone, but I'm becoming more and more agitated with people of the Craft polluting the idea that sex is anything but a natural phenomenon. Some people choose to represent the union of the God and Goddess symbolically by placing the athame in the cauldron and others choose to show it through the union of their own bodies in an actual representation. It all depends on the persons' preference.
Right now, I am reading a wonderful book on Celtic sex magick and I would like to reach out to those who are interested and tell them it's a wonderful journey. Your journey is different from everyone else's and that is perfectly fine. Don't listen to judgement and do what you need to do in order to continue your journey. Just remember to be safe in the process!
This is the book I am currently reading if others would like a reference:
