As long as you are aware of the risks, the best judge is you. 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.

The critical law to understanding the gravity of the danger is to understand that a person under 18, under California law, cannot legally consent to sexual conduct (Penal Code § 261.5(a) (defining minor)). “Dating” can certainly imply sexual contact, which is illegal between a fifteen-year-old and an eighteen-year-old.
