All I wanna be is cis het why meee😭

So i started to feel like a lesbian again and that i have to be one. I dont want to be one. I just dont. But being straight feel like a lie now. I question my whole life, my feelings and everything. The biggest indicator of this must be that i will be slowly 21 year old and ive never dated anyone and i dont really find anyone attractive and i dont even know if i truly was attracted to someone and im scared of relationships i might have trauma or have anxious avoidant attachment. Help me. I do feel lost. Really lost. I dont know who am I anymore. I feel like that i must have been gay my whole life now. I feel like an alien. I sometimes feel like 2 people are living inside of me.😞😞😞

I am a 18 year old masc lesbian with a loving girlfriend for 1 year, and I have been lesbian for almost my whole life and I have never been attracted to men in any way. flash to my past, My ex girlfriend who used to identify as a lesbian had cheated on me with a man. Recently I saw this tiktok of this masc lesbian turn straight and my friends and girlfriend made jokes I am going to turn straight for my male best friend. My male best friend came over and he’s a great guy but I do not want him in any way. when him and i were hanging out my mind threw in a thought it was “What if i like him”, i came back home and i had the worst panic attack and i felt so sick, i cried and i cried. ever since that day I have been struggling with intrusive thoughts, i don’t want a man in any way, and i feel comfortable as a lesbian but these thoughts won’t stop and they become worse when i see people say being lesbian is a phase or that i haven’t met the right guy or i’ll change in the future. i just want these thoughts to stop, i don’t want to stop being a lesbian ever, i love women so much and i just want all of this to be over with. i do not want a man in any way and im tired of my thoughts doubting myself and i hate the “what ifs”, I just want to be my old self, I want to be happy with my girlfriend.

just crying cause i feel like im never going to recover and just have to be lesbian, even tho i love my boyfriend so much. thoughts don’t even give me anxiety anymore idk what to do, im just so done, feel like it’s all real and that i want it(when i dont). any tips or anything, idk how to keep going
