Sexual orientation ocd

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’m 25 and never ever thought this before my soocd relapse. I have a bf of 5 years. Never been a high libido kinda girl. Don’t get me wrong I do get turned on by my bf but not like every day you know? - That had always been in the back of my head, is this normal and ok? But my ocd has latched onto the most scariest what if EVER. My brain is now saying How do you know you won’t prefer to sleep and kiss girls if you haven’t tried it: and it’s that unknown that is scaring the shit out of me. I DONT AND NEVER HAVE wanted to sleep / kiss a girl. But now my intrusive thoughts is all I think about!!! I don’t want I don’t want I don’t want??? So why does my brain think BUT WHAT IF??? I know ocd thrives off uncertainty which is why I think this is happening? But I don’t wanna find out or work it out because all I want is to be with my bf and marry him!! Is this just the epitome of OCD?

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?
