Very short bisexuality rant/feedback desired

I'm bisexual (cis female) but for the longest time I preferred guys and I eventually began identifying as straight. However time went by and I noticed that I was never actually straight and had always liked girls too. As time went on, I started preferring girls, but now I feel like I have no preference for one gender over the other.

Some people get mad at me and say that I have a choice between guys and girls, and they're right; I do...Until I develop an interest for someone. Then I don't have a choice on whether they're female or male... Because I have no gender preference.

I know this is probably a stupid question but is this normal? Some days I feel like I'm not even bisexual, but rather more gay, and other days I feel straight but deep down inside I know that I'm bi. Am I confused or what...?

I would also like to add that more times than not, I'm more turned on by girls (although I am still sexually attracted to guys) but oftentimes I'm more romantically attracted to guys. I do have the ability to be romantically attracted to girls...But just not as much as a guy I guess.

Additional feedback is wanted because I want to hear from other bisexuals <3
