There is a few ways you can answer that question.
First we have the multitude of sexuality scales, with the Klein Sexual Orientation Grid probably being your best bet. Here variable A and C would be most relevant and you would probably land on “heterosexual mostly.”
In addition to sexual orientation there is an Affectional orientation which may define you as a heteromantic.
Using both sexual orientation and affectional orientation you could identify as a heteromantic-bisexual. Or just use the umbrella term “queer.”
However you may not want to use these devices to label yourself or your sexual desires. In which case you will simple have to choose a label that you are comfortable with.
Hope that was helpful.
