doctor makes the difference
I used to dread this, too. Now, for the past 4 years, I've had a different doctor. She makes all the difference. It doesn't bother me a bit to go. She's just very informal, like talking to a friend. She does her thing quickly, and I'm back out the door.
My sister was complaining about having to go for her annual exam and how much she hated it. I told her it was no big deal and I didn't mind it...she looked at me like I was crazy!

I talked her into trying my doctor. Now she's been twice, and both times she's called me afterwards to thank me for telling her about my doctor. I guess I'm spoiled with my wonderful doctor!
