It's not important that you know someone is "queer sapiosexual". It's important that the person who is knows, and is able to describe themselves.

I'm a homo-romantic asexual, and it took me until I was nearly 40 before I understood this. I often wonder how differently my life might have turned out if I'd realised this sooner.

People often complain about labels. They're not labels - they're tools we can use to understand ourselves, and help others to understand us.
