Is it normal that my fantasies don't match my sexual orientation? what am i?

I am a female.
I am only attracted to females in real life, and have never looked at any males in lust. I have had one real-life crush (E.K. looked nice with that haircut, and was such a huge nerd. Can I be blamed?) and one celebrity crush (Aubrey Plaza, who is extremely charming. Look the cutie up.)
However, the majority of my fantasies include males. The males are always in power, and forcing me into penetrative sex. Afterwards I feel nasty. The male's physical appearance is never taken note of. Just a vague body taking a male form, in a very impersonal manner. Ofttimes the male is a false father figure. (Note: I am not physically attracted to my father.)
On the rare occasions I fantasize about females, it is much more fulfilling. I can picture their bodies, and how breathtaking they are. The sex is consensual.
Why am I fantasizing about a sex I am not attracted to?
Why is it so difficult to fantasize about women?
Who murdered Mrs. Nancy? (Find out after these words from our sponsors.)
No seriously, this causes a lot of turmoil in my life. Am I suppressing my sexuality? What is valid, my attraction or fantasies? Both?
