Okay, let's make this as clear as we possibly can.
If she got down on her hands and knees and begged you for it, and her parents provided written, notarized consent, paid for the hotel room and provided the condoms, you'd STILL go to jail.
Mom and Dad would go too, but you'd have no defense whatsoever.
The whole point is that BY STATUTE she is legally incapable of providing consent, and Mom and Dad cannot make the illegal, legal.
Is that quite clear enough for you?
Oh. That's why you were asking if it was okay to get her pregnant because she told you her family "is okay" with her being a Mommy at 14/15 ... because you didn't want to have sex with her.
Yes, obviously you don't want to have a sex. Uh huh.
If an adult has to ask if it's legal to have sex with a child ... that adult needs help we cannot provide here. And that adult has no business having sex with anyone other than his hands.
