Hello,

As an uncircumcised man I was wondering what the foreskin is supposed to do if you're having sex using a condom. I find that I only get the rolling effect of the skin and foreskin with difficulty, and it's a strain to therefore get a pumping action. Is this normal? Should the condom slow or stop the movement of the flesh, or are the ones I'm using too tight? Is the idea to prevent this sort of movement or should it be allowed? I don't want them to break or slip either way. Thanks.
