whenever i see cute videos of straight married couples together with their kid i imagine it with a girl and it feels like i want it :(

I keep seeing tiktoks of things that are like ‘things I did as a lesbian in denial’ or ‘things my not so straight straight friend said’ and I feel like I might relate to some!! But idk!! It’s kinda triggering me. I’ve had this 5 years on and off now so when it comes back the whole well you’ve had it so long you must be gay comes up. I have been with my boyfriend almost 6 years and i love him so much I don’t want to be gay (nothing weong with it - I’m just not and don’t want to be!)

When i have this scenario in my head : kissing a girl in my bed , i can image it very much mike i like it and it will come naturally I dont know if i really like it and i dont like that i like the idea Or That i just dont like the idea Also feeling really weird and maybe even sort of disgusted of my bf when i image the same scenario with him, or i feel like i cant image kissing him Wtf is this ?

And what is happening...let's say I come across a video of that person and then I stop the part where it triggers me and I deliberately imagine images of a sexual type, and if I don't feel anything, I look again, as if I want it or I have the urge to imagine it, i.e. I feel the need, and if I feel something or get a feeling in my groin and I feel like I fall into despair?
