I've been having a 'bad romance luck' streak. Every person I date/or get into a relationship with seems to only want sexual intercourse or overly intimate relationships. Is there a spell or something to help attract an asexual relationship/partner? I'm starting to loose hope in it.
A general love spell could work for you, something in the general area of "I attract a loving partner who is asexual" along with any other traits you like. Generally these involve manifestation or a release of intention via candles and/or sigils, but depending on your preferences the right spell may vary. Do keep in mind that casting love spells on specific people or to disturb one's free will is generally considered unethical, if that's important to you.
Also, as someone considering the possibility of being asexual, magic isn't going to solve something like this more likely than not. It's more of a matter of the time not being right and needing to keep your hope up.
I wish you luck! I know how frustrating something like this can be. If you need guidance with specific love spells and such, leave another comment or feel free to message me!
On a personal note, you should bring this subject up with any potential love interest in orders to understand each other's expectations so noone's time is wasted. Honesty is key to a healthy relationship.
As for attracting an assexual partner - it could be entirely possible. Wether you want someone specific to become sexually uninterested, as unethical as some would consider it, or generally attract someone who is originally asexual - you can cast a spell or series of workings that represent your intent.
As a hoodoo practitioner I would do a spell targeting the genitals. In folk magic they call it "flaccid penis spell/ limp penis". Take either a figure candle or anything that resembles the genital's of the sex you're interested in, and handle it with herbs such as poppy seeds (can be used both for confusion and shutting down sexual desires), weed and, etc. That's a general idea. I would also target the mind and soul, and probably go with a skull candle and speak my intentions to it. That's just a general idea, you'll have to design it yoursef.
But please keep in mind that when it comes to manifesting things you have to actively do a change in the physical world. What does that mean? Well, for example you could be open with potential partners about your expectations from the get go, mention it in your dating profile bio, etc.
My advice is less magickal and more mundane. Perhaps looking for groups or dating apps for aces would be a good start. That would definitely increase your chances of finding the relationship you are looking for. I know covid sort of puts a dent into things with one's dating life, however there may be opportunities. Best of luck.
