Throwaway account, so Im a below average guy on one end (3.9 inches or 10cm length, nothing more nothing less) and above average on the other end (5.5 inches girth)

And I was wondering because people always say "length doesn't matter as long as you have girth" which is something that I don't believe is completely true, I believe that even if you have good length but small girth it's pretty bad and vice versa.

I'm not that insecure about my size where it ruins my life, but sometimes I'll just have days where I think about it and wonder if it's enough, then go into a internet searching spree to see threads about people who have similar circumstances to me.

Sorry if this post is repetitive but I am really curious about people's take on this.

Also sorry if my English is bad, it's not my main language.
