TIFU by asking my boyfriend about our first kisses

So, my boyfriend (21m) and I (21f) recently got together before Christmas of 2024. We have known each other for the past 16 years after I decided to tell him my feelings. The topic of first kisses finally came up, we were on FaceTime mostly just making conversation. I told him my ‘technical’ first kiss was with my abuser before I met him (forced). When it came to his turn, he told me about a schoolyard kiss. He was in elementary school and it was with ‘some girl’ as a dare (as you know.. children do) and for hours I didn’t think much of it. But, it had gotten me to thinking about that time as I was reminiscing about our childhood memories and suddenly a memory had resurfaced that I hadn’t thought about in months. The exact same memory had clicked into my brain, and I mean exact.
The only thing that sucks is that he doesn’t remember who, or says he doesn’t.
But this revelation has changed how I see him, not in any bad way though. He was the first guy I could trust as a friend, someone I have been so comfortable with all these years without realizing why. I still have yet to tell him that I have a matching memory of the kiss, even though at the time I considered it my first as it was more sweet natured and more understood than what happened only the summer before we met.

Sorry for the long rambling, just had to get it off my chest.

TLDR: After years of knowing my boyfriend, I realized we might have been each others first kiss.
