In intercourse with my wife while trying to enter my penis to her vagina, the skin over my penis is getting back and it is causing some pain. But neglecting that if I enter forcefully my penis is becoming soft immediately and when I take out and touch head of penis which is now uncovered (pink colour) it pains a lot. And then I push my skin on penis to its original position. Later whenever I try to pull back the skin over penis, it irritates with some pain. As the head of penis is bigger than the hole of skin, it pains when pulling back the skin and when I am trying to enter into my wife vagina. Is there any solution for this problem or I have suffer like this only for entire life.
