hi! i'm queer (though technically bisexual). being unsure of your sexuality is tough. it took me many years to figure out who i was, and even now, i'm still not entirely sure. most people's sexual orientations are fluid. there are many scientists out there who have researched sexuality, and handfuls have claimed in times past that almost no one is completely straight. sure, some people know for a fact that they're going to marry a man, woman or whatever else, but the majority of humanity can acknowledge when someone of the same sex is attractive. after all, we've all got eyes!
if you want to go by a temporary label to make you feel a little bit better, bicurious certainly does fit your situation. i'm not sure how old you are, but if you're on the younger side and go to college, you'll probably meet plenty of girls who are also "experimenting" to see what and who they like. if you're past your college years, go to a gay bar and hook up with someone. and no matter what age you are... there's always tinder, bumble or whatever other dating app strikes your fancy. you're not the only one on this planet who thinks they could be bisexual, so don't worry about feeling alone!
you will figure this out eventually. as for how i knew i wasn't straight... well, i had a crush on my first grade teacher many, many years ago. of course i didn't know that girls could kiss girls and what terminology could be used to describe how i was feeling, so i didn't think about again for a long while. once i hit puberty in middle school, though, i started getting little crushes on some girls (and a few guys, too!) and after some research, i found out that being queer/bisexuality existed. i dated a few girls shortly after that and then, in high school, i had my first long-term girlfriend. i also had some boyfriends before that, but they were pretty mediocre in comparison. i haven't dated a guy since i was 15 though, so... maybe it was just immaturity.
i would give the advice of "if you know, you know" but i feel like it doesn't always work like that. some people feel like they might be gay or bisexual only to find out that they're actually straight after experimenting a bit. for me, "if you know, you know" was how i figured out my sexuality, but that's only because i remembered how young i was when i first questioned it. i literally feel like i came out of the womb predestined to be queer. other people are different, though. some people don't know that they're part of the lgbt+ community until they're middle-aged or even older than that.
imho, experimenting is the best way for you personally to go about this. obviously don't be reckless, but do have fun! even if you find out you're straight in the end, at least you'll be a lot less confused than you are now. but, if you do find out that you're bi, welcome to the community!
