Edit; Well, no serious rl relationships yet, I was dating someone 2 years older than me online for 2 months, broke up since I just wasn't feeling it anymore. We're still friends though.
I started "experimenting" when I was far too young, but I wouldn't really call any of the "experimentations" a boyfriend or girlfriend for me. I think my first somewhat "real" relationship was in middle school so I was probably 13 or something, she was my best friend who became my girlfriend, then went back to being my best friend.
I had my first boyfriend when I was seventeen, it was also pretty close to my high school graduation. Ahh well long to short, the relationship didn't last long enough and we just went are separate ways, well he did, I kind of just fumbled and dragged on the years to come
First time? I was like 8. Honestly it was actually a pretty decent "relationship" considering I was a kiddo, and it was actually better and more "serious" in comparison to my middle school ventures. He lived on my street, I had my first kiss with him, and we'd go swimming together. It was actually pretty cute.
My first long term relationship was when I was 16, I've been with him for nearly 3 years now and things are going pretty good. ^^
I was in 8th grade when I got my first "boyfriend" I say "boyfriend" because we lasted 3 days so nothing serious.
First official bf was in 10th and he was in 11th grade. I can't remember how long we were together though, maybe 5 months? Looking back at it now makes me feel silly to ever have said I loved this person.
