Then go if you're into dating, but be sure to check your state laws because you can still be charged should you two get intimate. I read a couple cases where the girl was underage and the guy ended up being charged (???). Oh..and I don't condone premarital sex, but if you plan to please remember to use protection!!
Oh...gotta add that my daughter is 11yo and I know it's different nowadays. That's why I say to use protection if you're into that kind of stuff. Dating can lead into intimacy so that's why I "said" what I did. I hope you young people think more about the girl and your relationship than you do about sex.
Good luck!
