I am used to BC by now.

I get a little anxious only because of what I may see.
As far as the procedure itself, I have learned to relax as best i can and not tighten up any muscles.
That makes it very tolerable.
Once you can learn to do that, it actually becomes pretty routine believe it or not.
So for those struggling, try to not tighten up. It will go much easier.
Also, put your mind in another place. I hope this may help someone.
