Are There 12 Year Old Dating Online?

You should not be even thinking about dating when you are 12

I don't believe there are any sites geared towards 12 year olds who are looking for a partner.  And, I have a feeling that if there was, it would be rife with older men posing at teenage boys.
Save the dating until you are 16 or so and in high school.

It wouldnt surprise me if there was. But dont do it. Your too young. Enjoy your childhood

Doubtful, and as Askjuliqhp said even if there really was one it would be crawling with sexual predators. You should probably stick with kids at your school or in your neighborhood. It would be easier to hook up with someone you really know instead of someone you met online.

First of all 12 is too young for dating and if there were such a site it would have to be policed daily to be safe and it would cost more than it's worth so humble yourself and mingle in your school and neighborhood......the best to you
