I found a site that gives men a way to quantify the amount of foreskin present when flaccid/erect on a 1-10 scale. I'd be curious to know what numbers people have, and how "satisfied" they are with that look (and for people who like partners with penises, what ranges are attractive to them). I'd also be especially interested to hear from men who were circumcised as adults or who restored their foreskin as adults, and what the before/after numbers are.
Personally I am a 9 or 10 when flaccid (depending on level of "chub") and a 9 or 9.5 when erect. Personally I'm not a huge fan of the look (among other things), so I've been contemplating adult circumcision for a while.
