It seems best to have a rest period to have the penis heal. That is when it does it’s growth, when it heals / your off days. I have read several “less is more threads” and they do seem to have worked for me. Make sure to read up on threads throughout the site, you will find invaluable information. Write some good information / notes on a piece of paper as well, so you do not have to go hunting for something you really liked.
From what I have read in surveys your stats are right at average. There are surveys that have shown slightly larger, but those surveys were just asking the person what size they were. Surveys that measured the individuals looks like they got 5.3” as an average length.
