Since this thread was started... I have been wondering a little whether the whole 'foreskin coverage' scale from CI-1 through CI-10, as covered on another thread, may be of some relevance in the context of condoms:

I come out roughly as a 'CI-5' on that test, that is to say: once my foreskin has retracted when I'm erect, it's not going
anywhere any more. And I've never had any issues with condoms in that regard.
However, I do wonder whether some of those who have more of a back-and-forth motion of the foreskin during sex might indeed be likely to experience some greater condom slippage, or the condom becoming 'tucked' between foreskin and glans at times. The latter is certainly something I've witnessed in the past... and it's just led me to consider that perhaps foreskin coverage
may indeed impact on uncut guys' differing condom experiences and levels of condom comfort.
Clearly, it's not an issue for most, or I think it would be discussed more... but for some, I could imagine it being a legitimate issue.
