I had my first boyfriend in 5th grade, if you could even call that a relationship lol. Basically all we did was pass notes in class, giggle, hold hands, and trade Pokemon cards.
My first kiss was taken at 18 but I guess it wasn't really taken because I kissed him. I'm happy that I waited though :3
My advice is to move at your own pace. There's certainly no need to rush things, especially when you could end up regretting it.
