It's not really that strange when you think about it. We are animals that have biological urges. However, we are social animals that live in a society. As a result, we must balance our biological pressures with our societal ones.

Let's just take the first example - teens who do not want to get pregnant.

I'm not sure what you find strange about this. Teenagers will feel the desire to have sex, but they (and/or their families) will be aware that having a baby at a young age can limit your freedom later in life. Thus, teenagers are told to either wait until they are older to have sex, or be sure to use contraception.

> It seems... strange, to expect responsibility and prioritization of biological goals from people at some times and not others.

Control over our base biological goals is a key part of what makes us civilised.
