Wait, what? Since when did QIA get added, and I don’t even know what Intersex or Aesexual is...?
Intersex is what used to be referred to as hermaphoditic - some physical traits of the opposite sex being displayed. For example, I went to school with a guy who grew (admittedly small) breasts on hitting puberty and had female body hair patterns. Usually a hormonal disruption during puberty, and easily corrected if diagnosed in time.
Asexual is precisely why is sounds like. Someone with literally zero interest in sex, though, like all of us, they can and do fall in love. They don’t shun it or avoid it, they simply don’t see it at all. In most cases, they do not even masturbate.
I know a lot about this sort of stuff.
