Since the "what fo I call myself" issue is timeless & unending, I figured I'd make a suggestion for future readers. I prefer the term "bi-dyke" over "byke", as it's pretty self explanatory & won't get you the same uncomfortable stares & silences that anouncing that you "are a bike" to new people will doubtless provide.
Queer can also apply to bisexuals who are attracted to more than 2 "genders", such as trans & genderqueer.
Or you could just tell people that you're a heterosexual, bisexual lesbian, if you don't mind the weird looks.
