What does asexuality mean anyway?
You want to be close to someone but not have a relation that may involve sex or is not based on a preference on a certain gender?
So basically you just really want to be good friends with someone?
Nah, it is way above good friends. Asexual is no the same as aromantic (= not interest in romantic relationship).
It is basically identical to any normal romantic relationship with your primary (and usually only) partner - in a good relationship, that's a bond much stronger than friendship, where the partner becomes as important as yourself (or more, depending on your personality). You plan your life with them, kids if that's your thing, etc..
Except that there's no sexual drive.
Which to any non-asexual person just seems pretty much impossible. Understandable.
To help imagining it, I'd describe it as a total lack of interest.*
Take me, I'm 100% uninterested in sports or cars - just entirely indifferent to the whole thing. I can imagine how my life (or my personality) would be different if I was as indifferent towards sex. I can definitely say my interest or prioritization in sex has dropped significantly since I was 25 or so - it's just not as important to me as it used to be, my interests have shifted.
That doesn't mean an asexual person cannot have any sex, they just do not feel the urge or drive towards it - they can be able to fulfill their partner's needs. Of course, that depends on if the partner is fine having sex with someone who doesn't really display any "initiative" and just kind of offers themselves on a by-need basis.
* That's just one aspect of asexuality, though.
There are those who are actively afraid of it, which can (but doesn't have to) have a traumatic background.
Or, of course, you can look at it like some manchild incel and just point and laugh or say idiotic crap like "just needs a good fuck huehue". *shrugs*
Parvati undoubtedly is an attempt at the first category - thing is, asexual people typically do not display such overflowing "poetic" romanticism as she does.
That's where the whole thing falls apart for me, it would be peak cringe even if she wasn't hammering her asexuality home. And of course with her openness towards an almost complete stranger.
Edit:
Please continue to confirm your lack of education and deeply rooted sexual insecurities by retard-rating a post about sexuality. It's like outing yourself
