I'm doing a poll to find out how much, roughly, the foreskin is "elastic" between men. In particular, ignoring its length that can be varied, it is important to know as occur the "exposure" of your glans, during erection, and the consequent "recoating", when the penis returns flaccid: for example, automatically, only in part autonomously, only manually. If you want, you can leave a comment about this poll and the results...
