Can freaking out that you’re actually asexual be part of the sexual orientation theme?

I need too know that I'm not insane, really. I am 16 and for the past two weeks, this has been completely ruining my health and happiness. I only recently came out as a lesbian like 3 months ago after a lot of confusion about my attraction since I used to think I liked men. At first, I felt so sure that I liked women, but lately, I've been having these unwanted thoughts about the possibility of liking men. I never used to feel this way, but now, every time I look at a man, my brain obsessively fixates on it. It forces me to imagine kissing him, loving him, things I don’t want, and then tries to convince me that I do. It’s painful. The thought of this fills me with fear and anxiety, leading to panic attacks and breakdowns. I don’t want these thoughts. I hate them with every fiber of my being, but I’m terrified that one day I’ll act on them and somehow like it. I used to think I liked men, but back then, I was in a very unhealthy space in a time of escapism and something deeply parasocial. I’ve only ever liked the attention and validation a man could give me, but these experiences are somehow treated as further proof that I’m "bisexual." I’ve never been in a real relationship with anyone, which makes my brain constantly challenge me—telling me, “You don’t even know what love feels like.” It won’t shut up. It keeps obsessively trying to make me prove that I’m a lesbian, testing my reactions and questioning my certainty. Is this normal?

Sort of a rant that probably sounds stupid and I’m kind of seeking reassurance… I’m still a relatively young teenager so I know I’ve got time to work all this out but I’m really confused about my sexuality. (I’m a girl) I’ve never been in a relationship (I don’t know if I want to be which is why I’m writing this) and sometimes I feel like I’ve never really had a crush and I just convinced myself that I did because I wanted to feel normal… but then maybe that’s false memory ocd??? I don’t really want to be in a long term relationship with a guy and idk about girls but idk if that’s just cos of my age??? Some days I hate the idea of ever dating, marrying or doing anything sexual. Other days I wish my mental / physical health was better so I could date someone! Everything I feel goes up and down a lot and idk why!? I have bad sexual intrusive thoughts that make me unsure whether anything that I think is real and my parents recently split up after not getting along for a few years. I don’t know if it’s my age, my ocd, my parents bad relationship, my sexuality (am I attracted to guys, girls? Am I ace!!!!???) Or something else but I have no idea who I am and I KNOW I’m young and have time but some other perspectives might help???? Can I ever be in a relationship if I have ocd like this? Also I’m really struggling not to compulsively seek reassurance and I don’t know who to talk to about all this irl I know I probably shouldn’t share this with random strangers but also idek if I care anymore 😭

Last night I took my meds to help me sleep and I kept waking up throughout the night with thoughts like “I’m really a lesbian now” or “I’m ok with it now, this is what I prefer”. I really feel like everyday for a couple of days now, I’ve woken up feeling more and more like my preferences have completely changed. The first few days was major anxiety, panic attacks, then I had a really bad double-bind and reversal spiral, and I became a little bit calmer since then. Now I feel like I’m managing the thoughts without anxiety or panic like I’m used to, but now it feels like I really want them and that I’m ok with it. Like I don’t care anymore. But the thing is, in between all of the mini spiral episodes I’ve had, I had these little moments of clarity like “I’m not giving up on my fantasies of men” or “I’ve always wanted men, that doesn’t just change”. But last night I’ve had really sexual dreams that I’m having trouble interpreting. I had one where I think it was me sleeping with a guy, but I woke up frantically because I think the roles got reversed, but I’m not sure. Another one I was a random woman with a husband, but I think the roles got reversed again so I woke up immediately. Both times it felt like arousal. Obviously I still care somewhat if I’m still here asking, but my brain or maybe me (I’m really not sure anymore) is telling me that I’m a lesbian now and I prefer it. It’s like I don’t care and want it now. It’s like I’m not even feeling confusion about it. I don’t know if it’s because of the meds, I’ve been distracted (family in town), because I’m in maybe quieter stages after two bad spiral episodes, or because I’ve really changed. It’s literally like I think being a lesbian will be enjoyable now but I don’t want that, even if my brain (and body apparently) keeps telling me that. I was told that ocd doesn’t change who you are, but now I’m worried that what I thought was background noise leading up to another spiral was suppressed self discovery (I’ve had two major soocd episodes in my life: late high school and now a few years later).
