There are demons who specialize in this area. Sitri is coming through loudly for me here. I’ve never worked with him personally, but his energy is really strong in this right now, so I’m going to trust that and speak up.
I know people who’ve worked with Sitri and had real, lasting changes, not just a one time lust hit, but deeper changes in how they carry, express, and attract desire. He’s not just a “get laid quick” entity. He can help, but he may shift more than you expect.
There are definitely other demons who can help, probably almost all of them in their own way, but Sitri is a known specialist when it comes to sexual magnetism, charisma, lust, and even confidence. I’m not going to spoon feed you a list, you’ll learn more by digging into it yourself.
But here’s the caution: this isn’t the shortcut it looks like. Demons are incredibly helpful, but they don’t do all the work for you. They move with you. You’ll likely be asked to change something, maybe burn something, energy, attitude, hygiene, whatever. This isn't an instant thing either. Yes, demons can give instant hits of whatever, but in most cases, they teach. Want it now with no patience? This isn't the path for you.
If you want something simple, easy, and low commitment, stick with spellwork. Spells aren’t lesser, they’re just a different tool.
Good luck.
