Ask Lilith to handle her? I mean if she’s lilith’s daughter Lilith will possibly look into it. Only “low” energy succubus require sexual energy as sustenance. “High” energy ones only do it for fun, intimacy, some don’t even care for sex like that. You could try and form a friendship just as a typical guy with female friends as well. If Lilith doesn’t handle it and you still do not want such friendships, try a lesser or greater banishing.
I’d also like to give you a bit of advice, holy stuff is nothing but MMO garbage lol. Unless an angel of the Judeo pantheon comes and does its thing, it won’t do much, infernal dark energy beings aren’t fazed by human holy stuff unless it’s actually charged with that elemental light energy a pantheon like the Judeo one has, or just any decently charged banishing/tool.
