I am sexually attracted but I wanna live my whole life single, by my choice

You can be whatever you want. Gay, asexual, bi, whatever your romantic/sexual attraction is. The problem is when you identify as an inanimate object like a f**king toaster.
Don’t get me wrong, there are some sexualities that, honestly, don’t deserve to exist. Like demisexual/demiromantic or greysexual. The only reason being because they already fit as another sexuality, but just use a different name.

Or you could just be straight

Asexual is not just not wanting to date ppl it's not feeling any attraction at all

Also I kinda agree with what you said

I know what asexual means and it's not a sexuality because it's the inexistence of it

Real, asexual ain’t a sexuality it’s just either being too immature to understand love or you just hate people

Deadass

And asexual isnt a sexuality
Its just lack of sexual hormones
