Question about foreskin

[OKexhibitionist]

As a circumcised male, I’ve been curious…..
Why do guys pull their foreskins over the head of the penis? Under them stroking then they stop and pull the foreskin over the head so that it flops around.

Are you talking about what an intact guy does during masturbation? if so, that's how many guys with foreskins masturbate, using their 'skins instead of a hand/fingers to stimulate their penises' sensitive head.
