Convinced I’m Asexual

So basically, I don’t know when this started, but basically whenever I look at a girl, a girl on a phone screen, or even a cartoon that’s a girl, I have this weird tendency that I like them, even though I’m straight. And though I am fairly young (still a teen), I’m positive that I’m straight, but my mind is giving me these weird feelings and signals that I’m not. And disclaimer, I do not have a problem with people with other kinds of sexualities, but I am feared for my life about this. I’ve honestly been keeping these tough emotions and feelings in me for days now. I don’t want to tell my mom because I don’t want her to think bad of me, and we also live in a Catholic household, so the thought of having a different sexuality is a lot on us. I’ve done some of my research, and since I’ve had many different types of OCD for quite some time, I’ve come to the conclusion that apparently I have SO-OCD or HOCD (basically the same thing.) I don’t know if this is true or not. But some other websites have told me that it’s just a part of being a teenager and growing up, and finding what love interest suits you the most, but I honestly have no pleasure with this whatsoever! I constantly think about, “oh, what if you like this girl right there?” Every time I walk past a girl, and sometimes my mind agrees with it, but deep down I don’t want this. And even sometimes, when I’m watching a video, or looking at boys in real life, looking at boy cartoon characters, most of the time, my mind tells me, “this boy is cute. I am attracted to him.” But other times, I completely disagree with that statement. Same with girls, so I don’t know. And also my mind tells me, or something in me tells me that the guys at school that I like, I don’t like them anymore, and instead I look at the girls, in which I know that I’m not attracted to, so it’s just a continuous cycle like that and I don’t know how to stop it. Someone please help because I don’t really know how to explain this, it’s just tough on me.

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 😭
