you decide what kind of attraction it is that you're feeling btw
if you're looking for labels to accurately describe the kind of attraction it is that you're feeling, to find the word that fits your attraction, that's valid, and i wish you luck. but if you feel that your attraction is this type of attraction, then it can't be proved wrong. like if i say my attraction to this guy is platonic, nobody gets to tell me i'm wrong about how i feel because of some hyper-specific criteria, regardless of what i actually feel for him.
if you say your attraction to this person is strictly aesthetic - then that's all you need. you do not need to fit any sort of criteria. you don't even need to label it at all.
your feelings cannot be proved wrong- the only person who can decide what you're feeling is you, even if the attraction you feel doesn't fit the definition of whatever word you choose.
the attraction does not need to fit the word, nor does the word need to fit the attraction.
this also goes for relationships, behavior, and actions. people often percieve kissing as the most romantic thing you can do, and yet others percieve it as sexual, sensual, or platonic.
if your relationship involves much physical touch, what would you call it? a sexual relationship? romantic? sensual? that's fully up to you- you can call it any word you like, regardless of what happens in the relationship.
this goes for others relationships too. if someone calls their relationship nonsexual or nonromantic, then you don't get to decide whether or not that's 'correct', regardless of what happens in the relationship.
you are never obligated to fulfill any sort of definitions.
