as one who grew up very uncut, I will respond to this thread slightly differently. 2 images which had huge influence on me.
As a "very uncut" guy, I was self conscious about my foreskin being much longer than then norm back then (back then, foreskiins were expected to auto retract fully during reection and lnot have overhang on adultt).
First image is from a then popular magazing destined to girls. While the image I could find on the net isn't higjh resoluted, the printed copy I had seen back then made the circ scar at edge of foreskin more obvious. While my original desire was to have self retracting foreskin, that image confinced me I also wanted one hat left tiop exposed when soft. (the other images in that spread jad fully retracted foreskin, something I underestmated because after my snip, my skin did end up fully retracting often when soft).
The second image came much later (had been semi cut for long time and had accepted I was no longer uncut). It was a key in getting the seed of desire for f
ull circ to germinate. (yes, the body is nice too
Obviously, by the time I went fro semi to ful, there had been plenty much more imagery that reached my brain, both Internet and locker rooms. But that image above made the concept of ME being like him very appealing.
