Well I've been reading the Swingers stories, the average dick size there appears to be 8 inches or more.
It's funny but the few women I've been intimate with have all commented that I was above average, yet I'm only 6.1 inches with a 5inch circumference.
My dad always told me that a bad workman blames his tools, ladies if you're not being satisfied perhaps it's not the size but technique that needs refining.
Having said all that my best asset is my tongue anyway and that's less than 2 inches !!
