There arent any laws around being in a non-sexual relationship where one person is under 18 and the other over. Once you turn 16 its not illegal for someone to have sex with you no matter how old they are.

Whats the oldest you can date at 16?

So, if youre 16, the minimum age youre supposed to date is 15; the oldest is 18. If youre 13, youre out of luck. The youngest you can date is 13 1/2, but the oldest is 12.
