am i gay? am i bi? should i care? help!!

hi! i (17M) have struggled with sexuality since mid-2021. i came out of the closet as gay in late 2020 to my friends (to their chagrin, sadly,) asked a guy out (who rejected me, sadly,) and have kinda lived in this "what am I?" zone since coming out. at times i feel an attraction to guys, and at times i feel kinda repulsed. (i think its important to note that i do look at gay smut often, like usually once a day.) as for women, im not very attracted to them but i get uncomfortable when the idea of having a relationship with one comes up, and my brain turns it into "well if you have a girlfriend that means you're not gay" which makes me scared for whatever reason. this has put me into a self destructive cycle for quite a long time, honestly! I mind my business, then something about women comes up which makes my brain doubt itself, and i exclusively think about that until i eventually calm back down. (This cycle is usually amplified when my attraction to men is lower, and the smut doesn't give me the same excitement.) Sometimes during these self-doubt cycles, i think of the idea of being bisexual, and i like the feeling of it, especially when i fantasize about being in relationships with other guys. Am i just a bi person going through bi-cycles without realizing it? i dont know!!!

tldr - im gay (i think) and go into constant self-doubt cycles. when i think of being bisexual during those cycles i enjoy that label.
