Not to sound harsh or rude but what you call "demon lovers" are literally superior beings and from our existence level they are god's and goddesses to us, spiritual partners on the astral plan require open spiritual sense, it's not tinder or any crap like that. And you probably didn't mean in that way, but it's better for your personal growth if you focus on the material plan for now. "Succubi and Incubus" are not for everyone, this doesn't mean that those who have it are superior it's just a different form of relationship, but still very deep and on higher levels. Plus doing a ritual asking for one will not manifest them in flesh and bones, for actually seeing them you need to spiritually advance first.
And trust me if you start advance, the right girl for you will show up in your life, you could do a working to find her that's more convenient and suitable in most cases.
