Chiming in here, I guess I was the same. First two wives were not cock lovers, so never really said anything, and even if a guy thinks back to the highschool & college days when there were open shower rooms, you don;t get the same perspective looking down at yourself as looking at someone else, so you don;pt really know you are significantly larger. I always knew I was a bit larger, but not by as much as I am. Also, you don;pt see yourself hard compared to other guys at all (unless you are gay or involved in group sex), and size comparisong differ greatly between ahrd & soft. Mine nearly doubles in length between soft & hard... So again, I really didn;t know... Then abut 5 years ago I got into group sex (mostly MFM's with couples, which I totally enjoy!), and only then did I discover things were that much different. Also posting my pics & vids & the comments I got back helped me understand. Wwtching Porn I thought I was pretty much normal & soetimes even wondered why some guys in porn were referred to as large whe they were smaller than me, but passed that off as creative marketing...
Oh well, I'm thankful for how I'm put together...
