My first four letters is something you see in a parade. My last three letters is something you shouldn’t ask a woman. What am I?

You can peep through me, but that's not what I'm for. I am the gatekeeper of your door.

I am the stone that holds the rest, Placed at the top to pass the test. Without my weight, the arch would fall, I lock in place the curving wall. WHAT AM I?

Behind me lies what some call a soul. If your feeling saucy, just give me a roll.

Give me food, and I will live. Give me water, and I will die
