How old were you when you first started grinding with people at dances?

I was grinding with guys in 6th grade. I guess it's because that's when all the dances started and people actually danced. And because I wasn't afraid to like I would've been any younger. And also, do you grind with girls if your a girl? I don't. i think it's for bisexuals. It's weird. i only grind with guysHow old were you when you first started grinding with people at dances?

if you only grind with guys it makes you sound like a whore
sixth grade also. and i think grinding with girls is fine if its in a grind line but wierd if its just two girls.
