I agree, I don't actually have a spiritual father, or a even a God that I predominantly work with. I also don't feel an absence or a need to seek out such a thing; you of course could be different.
I am very close to Isis, but Osiris just never called to me, nor has any other male deity- or at least for more than the duration of a specific working.
How did Loki find you (I assume that is how it happened), or how did the relationship start?
When you take that into consideration, the process will most likely be similar. If it was spontaneous at first, that is most likely how it will unfold, if it does/needs to.
