ELI5: Why do we feel ashamed about our bodies?
(further elaboration inside)

What I mean to ask, is why did people start viewing them as shameful to begin with? (especially with such zeal, sometimes) Why do we get embarrassed about it if, say, our jeans rip by accident and we're like "OSHIT COVER THAT SHIT UP RIGHT NOW".
I can see where some possible sources of this attitude might come from, but I'm not a hundred percent sure. Any insight is appreciated.
And thanks in advance for (genuine) answers.

It's just habit and cultural conditioning. We're taught from a young age to cover up when other people are around and throughout our lives we (or at least most of us) are so rarely exposed in public that it feels weird to do otherwise.

These feelings can build up around almost anything we do habitually. For example, do you have a watch that you always put on before you leave the house (or it could be a piece of jewellery or sticking your phone in your left pocket)? What happens when one day you forget to put it on? You won't have walked more than a few steps from your front door before you'll feel a tingling in your wrist. Your body knows you're doing something that is against habit and it makes you feel uncomfortable.

**EDIT:** Just re-read your question and it looks like you're asking more along the lines of why people hold that moral view that nakedness is indecent. That has to do with the idea of sex being something private (note that it's the sex organs that people worry about most) and therefore anything to do with it should supposedly be hidden when in public. It's just like you wouldn't be buying something in a shop and start chatting to the cashier about your sex life; you wouldn't get your bits out in front of them either. At least, probably not.

As to where prudishness comes from, and whether it's a good or bad thing, that's another matter.
