Dating is ok, but sex is a different story. The eldest one in the situation could be charged with rape or sex with a minor.
It isn't illegal however if you have sex it can be illegal if your parents take action.
I'd say go for it, as long as you use condoms.
Yes, with parental consent. But you can't have sex, though.
yethhhhhhhhhhhhh

Dating is not illegal; sex is illegal.
If it is OK with her folks and "dating" is as far as it goes.

In certain states, it depends on the consent age. I live in Iowa and a 16 year old can date a 19 year old and have sex with them.
16 is the age of consent. And if you are only "dating", there's not much issue.
yes, if you have the 16 year old's parents consent.
