Haha,exercises as in stretching it everyday when in the bath?Seems like a lot of uncircumcised people here have trouble with their foreskin 

Sensitive..I dunno though,guess you could ask the doctor,actually i'm now doing 'exercises' on my foreskin too,can't really pull it back fully yet,so still trying yea 

But,is it true that when you are having intercourse,the foreskin will be pulled up and down too?

Stretching is a solution if you dun wish to be circumcised.

However,  make sure that u stretch it a min at a time.. if not, ur foreskin will feel sores. Practice makes perfect..

As for my case, i start stretching few months back.. cant rlly pull back.. the intercourse was lotz of pain at first.. now slowly numb to it eventhou i still cant retract my skin when erect..

btw~ im still doing the stretching.. if not, will ejaculate very fast due to the momentum from both sides..
