We get asked thing like this all the time, especially from people who have never cast a spell in their life.
No, there is no single demon that can make all your dreams come true with the signing away of your soul or whatever rubbish people believe from movies and books. Real magick does not work that way.
If all someone had to do was call up a demon to bed any woman they wanted, we wouldn’t have ignorant, basement dwelling, morons committing violence just because they can’t get laid, and yet, sadly, we do.
Magick will not make yours, or anyone’s, Hollywood fantasies come true. You will not become rich overnight, and you will not suddenly engage in fantastic orgies with supermodels, regardless of whether you suck Satan’s dick, Lucifer’s dick, or the dick of Yahweh himself.
If you look like a potato, don’t expect women to drop to their knees just because you pray to Satan or whomever. Real world rules still apply. You still have to make the effort to take care of yourself, go out to places to actually meet people, be polite, and not be a creeper stalker or abusive asshole. All magick does is give you an opportunity via coincidence.
