What's it like getting your ears pierced or gauged?

So I'm considering getting my ears gauged and I'm just curious as to what it feels like? Is there any advice you could offer for a first timer like myself?

-What pain to expect

-How small must the gauges be so that you can take them out and they'll close up, just in case

-How you care for newly pierced ears

-Any other tips

Thanks!
