The summer between 6th and 7th grade.....can't remember how old I was. He was my first love (crush, whatever you want to call it.) That's as far as it went....by the end of summer we didn't even know each other anymore, lol!
Ohhhhhhh boy....I had my first french kiss at the age of 7
But my first boyfriend and "serious" relationship was when I was 11, I was even allowed sleeping at his house since his sister and I were good friends so there was all kinds of "kissing"
Probably when I was about 9 or 10. An old, dear friend lived 3 houses down from me. We basically grew up together. If she hadn't moved away when I was 12, we would probably still be together.
My first kiss happened when I was in third grade....I was over at a boy's house (we were just friends and we were part of a group that hung out together) and we were working on a model plane. Suddenly, he just leaned over and kissed me. Out of the clear blue. And then we kept working.
I think my first serious kiss was when I was around 12 or so and it was from my DH. Well, he wasn't my DH then, of course, but he says he knew. And we did get married when I was 16 and he was 19. That was 40 years ago.
At 15, my best friend's boyfriend gave me a peck once because we both said he wouldn't do it. Then she turned and gave me a peck and told him to give his [male] best friend one He said "Heck no!!" and ran out of the house.
