I'm constantly scared that none of my feelings and attractions towards the same gender are real, and that they're just OCD, or even me forcing it

Im a 21 year old female in a straight relationship with the best guy a girl could ever ask for. About 2 months ago, I went to get coffee with a friend and as I dropped her off, I got a “weird” vibe from her and the look she gave me which lead to the thought of “should I kiss her”….Ive never had a thought like that before and I never have ever wanted to kiss another girl. I have also never had a desire to be with another girl (sexually or romantically). Now though, I have had one other experience of being with a different friend going to get lunch and it felt weird. Ever since then I have been on google non stop with hundreds of different searches, questioning if im lying to myself of my boyfriend, wondering about my past relationships even though Ive only dated boys, been attracted to boys, crushed on boys, etc… boy crazy! Reading on other forums has been a big thing too or doing quizzes. I believe its SO-OCD but im so scared that what if its not. I am in therapy and actually had two weeks of not even thinking about it or googling it until yesterday. I dont know what to do.

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?

As a lesbian with SO-OCD, I feel so helpless. It's truly exhausting because no one I know understands what I'm going through. The first response is always, "You're just confused" or "You don't have to know yet." But that's not the issue, I do know. I just never see any lesbians with SO-OCD so I feel so invalidated. These thoughts flood my brain constantly, forcing me to analyze my reactions to every man I see. I feel trapped in an endless cycle of "testing" myself, trying to prove that I don't like them. But my brain fights back, telling me I do want to love a man, making it feel real even though don't want it. It's terrifying. At this point, it's hard to even hold onto my identity as a lesbian because I'm so overwhelmed. I don't know if this is what real attraction is supposed to feel like, and that fear eats away at me. The truth is, when I think about being with a man, all I feel is disgust and fear-but my brain twists that into doubt. I hate it. I'm at the point where I'm scared I'm going to have to accept something I don't want because I don't know if this will ever go away. I miss who I was before all this.
