hi valerie! ^_^
re: choosing labels
hmm... honestly? in my opinion just choose whichever label you like best! (easier said than done of course....)
i think "not knowing which specific label fits exactly right" is an experience MANY queer folks go through... and sometimes we end up finding the specific label we're looking for, other times we just say "screw it" and go with a less specific label, like queer or arospec etc.
for example in my case, i'm also not sure if i experience romantic attraction, and how much, how often, etc. ("demiromantic? grayromantic? aromantic? aahhh") but eventually i just decided to stick with aromantic, because i like how ....no-strings-attached it feels i suppose..? for me, describing myself as aromantic means that i don't have to feel attraction, and that feels very freeing to me, and i feel at home with that label :)
i have also heard of people choosing labels based on which pride flag they like better lol
on the other hand, specific labels can of course help you to connect with like-minded people and can help you understand your specific experiences better, so maybe you could just try out identifying as both lithromantic and aro? or either of the two? :) you could just use those labels for a little while and see if they fit and feel comfortable and if not, you can always try different labels!
i hope this helps a bit! ^_^
