Yes we do. I have some 30-40 dives done with Advanced open water diving license, but since I only dive in exotic places 1-2 we visit times a year, I always need a full refresh as first dive on every vacation. Not having any scuba equipment at home, the things life all safety and equipment checks, even though easy, just fade from my memory.

I recall, when doing my first real dive (not training in 4m), in Croatia, the instructor took us to 33m. I was showing him this on depth meter, he just signaled OK with fingers. The feeling of being so deep that we didn't see surface anymore, on a first dive was a bit unnerving.

I also have similar experience to yours with shipwreck, although with some 30 dives it wasn't so scary. But we were swimming through narrow passages of very old shipwreck from WWII on Bali, and I felt how tubes are touching the walls. It wasn't a big wreck, but I wouldn't go to this kind of inspection on my own, just followed instructor.

One thing I noticed - a minority of folks are so arrogant they barely follow instructor and do what they want, ie not following the group, swimming lower than instructor etc. Can't comprehend this, I mean you are literally reminded by all senses how you are in very unfamiliar environment, yet some can't show any respect for it, even though they don't have much experience themselves.

Anyway, a very cool sport, although its one way to realize how messed up our environment is, when you see more and more corals dying literally just over few years.
