I like women but I also like cock but I'm not otherwise attracted to the male body at all. Wtf is my sexual orientation? AITA?
I like women. I like the shape and curves of the female body. I like boobs, I like asses, I like pretty vaginas. I also appreciate and am aroused by a nice cock. I'm however not otherwise attracted to the male body. I like femboys as long as they have a feminine-like shape and curves, as many of them do.
What incredibly enough hasn't been brought up yet, is the distinction between gender preference and genital preference. In heteronormativity they're assumed to be the same, but in reality they're not. This way of thinking also lends itself to the flexibility you're describing; note the word "preference".
