Cassexual is an identity where one feels that one is indifferent to the idea of sexuality, and believes it is not an important part of their identity. A cassexual individual may be on the asexual spectrum, but does not have to be.
It is similar to, but is not the same as pomosexual, in which one denies labels for their sexual orientation. Cassexual people can have a sexual orientation, but they do not care about it, whether if they are allosexual or asexual.
The romantic counterpart to cassexual is cassromantic.
Etymology
