You're not necessarily
bisexual, you're not necessarily
bi-romantic, merely bi-
crush-ual. You find yourself
crushing on, or
infatuated with, a person or persons of a
sex or
gender whose persons you don't find yourself interested in doing anything
sexual or
romantic with; you're merely crushing on them.
Doesn't necessarily rule-out being
heterosexual or
hetero-romantic (sometimes mashup-spelled
heteromantic), but would seem to rule-out being strictly
hetero-crushual.
Potential alternative terms:
bi-infatual;
bi-infatuated.
As with all of these matters, you can be a little, a lot, or totally, bicrushual. (
Demi-bicrushual?)
Similarly, you choose how you identify yourself. Every rule has exceptions! (Except this one.)
