Straight gal, lesbian fantasies???

Okay, so, Im 17 and I'm straight girl..
The only thing is I really want to be with another girl
Ok I'm very attracted to men but for a little while now I've been sexually attracted to women
I've never been in love with women only with men
And when I think about mens genetalia I am very grossed out
Not that the female genitals are so great.. Theyre kinda gross too..
Everytime I masterbate I either think about lesbians or watch lesbian porn...
I do love men tho
Is there something wrong with me??
Maybe I'm bi...
I'd this normal?
