It's painful for those with phimosis because it's like giving your foreskin a really harsh so-called "indian burn", like young kids do to their friends, because while we have more skin than most uncut folks, the band of skin that normally rings around the middle of the head to the tip is significantly less elastic than normal, and causes discomfort when one attempts to pull back. During intercourse, there is repeated back and forth pulling on the foreskin, so you can imagine that if there is discomfort with even gentle pulling back, then there is a whole hell of a lot more discomfort trying to pound some pussy. Especially if she's tight/tiny ;D

But thank you everyone so much for your feedback. I will look into the cream solution. I just wish my frenulum would make as much progress as my foreskin has. All good things come to those who wait, I guess :P
