How to figure out your instinctual stack when you are asexual

A couple of years back when I just got into instincts, I remember there being quite a push for 'inclusive' description of Sx instinct (not saying it's correct, actually wondering about that, but just saying) that said something along the lines of 'intense desire to merge with object of passion, be it a hobby, a person, etc. I also saw asexual Sx Doms who used their description for their personality. I am a bit surprised but most Sx Doms nowadays are a bit more 'traditional' as I see a lot of talk about them prioritizing relationships, being sad without no relationships, wanting to experience intense emotions with 'chosen someone', etc. Not saying anything it's incorrect, again, but I am used to relating to that old definition of Sx that includes seeking emotional intensity, intense attachment to something, not necessarily someone. Who is right and how does one figure out that being asexual?
