Is it normal i question my sexuality everyday

As a straight woman I wonder if it's normal to question my sexuality pretty much everyday??
I have even wondered if I am a lesbian but that makes no sense due to my attraction towards men, yet it does make sense since i'm never attracted enough to have sex with a man. I can make out if I push myself... I mostly fall in love with men in my head. My idea of a specific men...
My romantic projections...
I'm great friends with some men and sometimes I wonder why I can't be in love with them. I always feel about men that I "should" love them so I sometimes force myself to fall in love with a male friend... It works for days at best...
And it's not even real, it's based on pressure from myself.
I went on tinder to search for women a few times but no luck.
It's almost too easy to get dates with men on tinder but when it comes to women you're lucky if you get a single match...
And even more lucky if they bother talking to you!...
Not to mention how a majority are just freaks looking for threesomes with their gross boyfriend... Well I guess tinder is all about hookups to many, but where else does one find queer women, as an introvert especially???
I feel like i'll most likely end up with a man anyways...
it's easier and i'm not the type of person who puts myself out there. So I wonder if it would be fair to whatever man I end up with. It would be if i'm just imagining things and questioning... Is it normal that a straight person questions their sexuality on and off for several years???
