It’s a type of of magick that uses sexual energy for power. The simplest form of sex magick is to visualize a goal you want to manifest at the point of orgasm. A more advanced method is to invoke a deity into your lover’s body and then make love to that god or goddess. You can also use sexual fluids to charge talismans and amulets. Sexual energy can also be used to give extra oomph to rituals such as the Lesser Banishing Ritual of the Pentagram.
