What do you mean? I said "straight person" and "preferred sex" - there are two genders, and both terms I used are gender neutral, so could apply to either. I'll rephrase then:
A straight woman can find an otherwise attractive man repulsive if he had a crappy personality. She doesn't suddenly have a whole new sexuality just because persona overrode genitals.

Likewise, a bisexual person who prioritizes personality doesn't have a whole new sexuality. It's just for them looks/genitals aren't the most important thing. There's absolutely no need to invent a new label for that.
