Am I (21F) straight if I watch female porn?

Hi, I've never been attracted to a woman in real life, as in I've never wanted to make out with another woman and what not, am only attracted to guys. However, in terms of watching porn I find watching women much more arousing than watching men.

On nights out (i.e. drunk) when I was single, I never actively looked for/initiated with a woman and I only looked for guys/found guys attractive, however when I watch straight porn I am always more inclined to watch the woman than the guy.

Is this normal? Or is it strange? I'm not really sure what to think...
