In that situation you’re fine, he’s fine. If anyone is giving you grief over it they’re mistaken. Also these laws are to clarify what is abuse of children, not hassle young people in relationships. Example : an 18 year old and a 13 year old “dating” is not a relationship, it’s child abuse. A 16 year old and an 18 year old dating is a relationship. I was married as a teenager in Massachusetts to a slightly older man and this was a constant topic for people around me.

Edit: after reading further and seeing that you’re concerned about homophobe parents lashing out at your bf, again; you are completely fine. Anyone trying to start trouble for either of you and basing it on sexual abuse ( which is what they’d be claiming) is going to be ignored.

Absolute worst case scenario is a cop knocks on the door to make sure a child isn’t being abused, which happened to me, it’s their job and if it’s called in super vaguely they might (“my teenage son is staying with some older man”) Most likely though they’d ask your parents how old you are and tell them you can stay wherever you’d like at 17 years old.

I’m sure you are okay in this situation. You can ask your insurance company for information on what to do in an accident for future reference. Print it in your first language and keep in the glove box. If something happens again it will be less stressful for you.
