I'm kinda the same way. It feels as if my sexuality fluctuates and its hard targeting what it is exactly. Now I've quit trying to label myself because it doesn't work, but when I have to I just say I'm queer. "Queer" now is an umbrella term used to describe anyone and everyone within a sexual minority, that includes bisexual,asexual,and like the second person described hetero-romantic bisexuals.
