biblical marriage help

Hey! Me and my boyfriend are minors, and we have a couple more years till we aren't. We really want to get married.

We have been dating for 5 years. Completely serious and loyal since day one.

We have messed up a few times sexually, so the biblical action to take next would be to; get married.

"But if they cannot exercise self-control, they should marry. For it is better to marry than to burn with passion." 1 Corinthians 7:9

" If a man seduces a virgin who is not betrothed and lies with her, he shall give the bride-price for her and make her his wife." Exodus 22:16

In the bible times, this would be perfectly normal to get married at our age, but now for some reason society has changed and it is illegal unless you have parent consent.

We cannot get parent consent because in order for them to understand why we can't wait a few more years, we would have to explain the sexual thing and they would absolutely freak out.

We know we are going to stay together. It tears us apart that our mistakes got in the way between us and God. We know He forgives us, but it is so hard since the temptation is always there. We have set boundaries, but even then the temptation is just so strong.

This is the only solution we can think of.

Does marriage have to be legal? If so, is there a way we can legally get married without parent consent, being minors?

If it doesn't have to be legal, what constitutes a biblical marriage? The bible, from what I know, never says it has to be legal, just says that it needs to be between 1 man, 1 woman, with witnesses and someoen to unite them. It is a covenant between the couple, and God.

Back in the days getting married at our age was normal anyways.

So please, help me find a way.
