[Marvel/Spider-Man] Why does Peter continue to act like a pushover after getting powers?

He finally has the means to stand up for himself like he likely always wanted, so why not use it?

You know how with Batman, the Bat is who he really is, and Bruce Wayne is the mask?

With Peter Parker, it's the exact opposite.

Peter Parker is actually a geek, genuinely a nerd. He is shy, awkward, and nervous. He doesn't see himself as powerful or commanding or cool.

But he *does* see Spider-Man as all of those things. When he puts on the mask, he becomes someone else ... some*thing* else. He becomes the person he wants to be.

That's also why he cracks so many jokes when he's fighting; it's not just to throw off his enemies - though it does - it's because he's actually terrified of the insane situation he finds himself in, and running his mouth is a nervous reaction to that.
