I've never experienced any pain during a pap. Haven't heard any of my friends complain about pain, either. But as far as embarrassment goes: Dennis is right, the doc has his eye on the prize. And also, the doc has seen a million of "them." (Doing a pap is as routine to the doc as it is for you to serve coffee at Starbucks.) Also, the pap takes such little time...you'll be surprised when the doc says it's done already!
How's that for a pap talk.... er, I mean pep talk.
