The dinghy in and out is really not a big deal -- just get a good stable one.
It is if you're rowing into a strong headwind. More then once I was unable to make any headway rowing out to the boat. This was Monroe Harbor in Chicago and we were the third row in from the breakwater, maybe 1/3 of a mile. One time I rowed for over an hour to get to the boat but never made it. And I was young then.
Regarding the introvert thing - I think I qualify for being an introvert but being in a slip never bothered me. But one time we backed in and I immediately realized everyone walking the dock had a nice view into the cabin.
Last time I did that! Never got those Europeans.
