Is polyamory a sexuality?

su

Do you believe poly is a sexuality, as in do you think it's on the same level as hetero, homo, bi or ace? Is it something different?

Do you think it's something some people are not capable of, or some people need to be fulfilled? Do you think everyone is capable of it, or is it not realistic at all?

(note: the conversation is about polyamory, not polygamy)

Edit: i’ve seen the argument that poly is not a sexuality because sexuality is about who you are attracted to. So for those who agree with that argument, do you feel like ace/asexuality is not a sexuality since it doesn’t refer to WHO you are attracted to, but how you feel the attraction?
