what am I?

Hey, im Nicolle (she/her) and I wanted to share my story about sexuallity so see if someone helps me finding this out. (To my friends, i'm bi; to my family, i'm straight; and to myself, I genuinelly don't know).

It all started when I turned 11yo, I hadn't a lot of sexuality questions about myself and was okay with the fact of liking girls. I flirted and "liked" of a friend of mine. On the last day at school we kissed (Simple kiss, not french, ew) and I really liked it. But we didn't do anything after that, we just kept being friends and we still are.

As I turned 12-13, I just liked boys, but in a forced way. I never ever felt that I liked boys in a real way, but i'm attracted to them. And would deny so much to ppl at school if someone asked me if I liked girls, althought I had kissed one. With my friends, who knew who they were, I always asked what they felt when they found out, how they knew, etc (They always answered with "you just know"). 3 years after that, i still never had a real relationship and not even flirts.

One thing that really got stuck in my mind was the "you just know", because at 14 I could swear I started to know.

But now I question myself. And the questions I have are:

Was I forcing myself to be something i'm not just to feel part of a place? (In both straight or gay ways)

Am I really attracted to women/men or I just think they're pretty and am mixing everything up?

Is it real or just a FOMO i've been feeling since 11?

And some things that make me question are: 

If I see a woman or a man on tiktok or whatever I will feel attracted, but on real life, I feel nothing 99,9% of the times.

I imagine myself dating both, but when I think of marrying, I only see men.

I liked a lot more men in my life than women, but is that because i'm forcing myself because its "easier to like boys", so I never look to girl in that way?

Help.
