I dunno if it really was a relationship but my first kiss was when I was 8 or 9 and me and my best (female) friend. Well we spent every single day together since we both went to a strict catholic Boarding School, and then it just Kind of happened at some Point, to be specific.. at night before we were going to sleep and we were like building up a "pillow fortress with a lot of blankets" and we were super childish haha. We often cuddled together and we shared a room together which was sooo great.
Never really told anyone about it now that I think about it... woooow. Well she gave me a necklace, which I later on lost somehow, and after I got into another School we lost contact. She was really pretty, helpful and always helped me when someone was bullying me (I was super tiny and sassy and got into a lot of fights).
