I posted this in lgbtqia+ but I thought I might also get some help here

Hi. So I’m 17 and have identified as bi or queer for most of my teen years. Recently though I’ve been having a bit of a crisis about it. Sometimes I wonder if I’m faking being bi to be “different” or something like that, cause I don’t always feel the same way about girls as I do guys. Like I don’t really get of to lesbian porn and I don’t fantasize about girls when I masterbate. I also dont really wanna date anyone regardless of gender?? Like I’d totally like to kiss girls and guys and have sex and all that, but I don’t ever feel like I wanna date or fall in love and all that. I think girls are really pretty and they make me feel all fluttery and hot sometimes, but I feel different when I see a hot guy. Do bi people feel the same way about all genders, or does attraction feel different for each? Also my attraction seems to fluctuate, like one day I’ll find one gender attractive and then the next I’ll think that I was faking it and I’m just straight/gay. Does anyone have any advice to help me figure this out?
