Minors having sex

In California it is illegal for two minors to have sex if they are under age.
What would happen to the two minors if they were caught having sex by
someone? Not just anyone like a friend or parents but like the law or something?

it's not illegal as both of the minors are under 18 , it's only illegal when one of the people are over 18 and one's a minor

It depends on where you live, but I'm pretty sure sex is illegal if you are under 16.

Because the circumstances at the time this act was caught would probably play a lot on what happens --- For sure... SOMETHING is possible. but there's more to the law than just the strict ages of the minors.

The acts that were witnessed, the situation at the time the minors were caught.

I'm no lawyer --- but that's how I read this:

California
§ 261. 5(b)-(d)
Anyone who engages in an act of unlawful sexual intercourse with a person under age 18 and the actor is not more than three years older or three years younger, is guilty of a misdemeanor

Anyone who engages in an act of unlawful sexual intercourse with a person under age 18 who is more than three years younger than the actor is guilty of either a misdemeanor or a felony

Any person 21 years of age or older who engages in an act of unlawful sexual intercourse with a minor who is under 16 years of age is guilty of either a misdemeanor or a felony

In short --- the male minor will likely be spending time in jail if the court determines that the law and decisions of breaking the law warrants it...

The male also will be considered a sex offender in most cases too!
