Anybody Else Think This

Does anybody else ever get really pissed off because of judgement from other people about your age? Like, for example, teenage girls who have sex or even get pregnant are told that they're way too young to be thinking of these things and even doing them... But that's what our bodies are made to do? I'm not saying that I don't know that having a child before you've gotten anywhere in life can be a major obstacle, but if someone chooses to do this why are they shamed for doing so? If we weren't meant to do these things then our bodies wouldn't enable us to.
