Personally, I will never be able to experience that regret.
As for the few people I know that have waited, most regretted it, but not all.
My personal thoughts are that if it works for you, great, if not, then don't. But in this particular case, it's a matter of compatibility and it helps to know beforehand. I understand the reasons why certain people wait though, so, we all must live and learn in our own ways.
