My foreskin was also very tight, so on advice of a neighbor/ doctor, I practiced retracting it and leaving it as such for as long as possible. The skin texture changed initally....and I was advised to use vitamin e oil and cocoa butter, which really did seem to make a difference. I did this for weeks or months until it stretched and slid over the head easily. Its still not like a loose hood. If retracted when erect, it STAYS unless I move it. No observable loss in sensitivity, because I really only keep it retracted when erect. But do not recall any swelling. My feeling is that that too will stop when the sking re-sets itself.
