>>122901709>Biological adulthood is reached when an organism becomes capable of reproductionYou're talking about this like human bodies aren't a fucking mess when it come to developing.
A girl can technically get pregnant before she reach double digit but that's going to ruin her development and can leave long lasting damage, if the baby is even viable. And that's without talking about her mental state and how fucked up she'd be growing up.
Same with teens, there's more to making a baby than fucking and popping out a crotch goblin, they may be physically capable but you're going to have issues because they lack the world experience to properly care for it.
>How can you check whether someone can give informed consent or not? If there is no way to check whether or not X, X is useless as a basis for making judgements.You can make assumptions based on age to some degrees, and you can just talk beforehand to gauge the situation.
Don't stick your dick in crazy, but don't stick your dick in dumbass either
