As with what Daisy said, why would you want to summon a sex demon? All they do is basically use you and dispose of you. Maybe if she's like that, it's becuase she might have to try and find someone else to use.
Well, I agree with what the others have said but I guess what's done is done. Just a little advice, you should be really careful when you're feeling lonely and work magick. You can really tamper with a spell, and things can go very wrong.
People think that incubus and sccubus are evil spirits. they are not evil spirits, they are just sexual beings/or demons what ever you want to call them. I do not believe demons are evil. But i know everyone has their own opinion, Just make sure to know what are you doing, when you do magick. Make sure you repsect them as they are spirts. Spirits should always be respected.
