I totally agree with you on that Ric. The climax is not as important as the overall experience. It's never been important to me but, as KSteve says, some ladies don't consider their job to be complete, if the client doesn't cum.
As to the op, there are a lot more malfunctions by clients than would be readily admitted.
It has happened to me on occasion but I still enjoyed the company of a beautiful lady, so no biggie(excuse the pun)
The important thing is to just relax and enjoy yourself and let it all happen in it's own good time.
