Suggest Remedy To Make Foreskin Move Back Freely

hello sir, this is vinod from hyderabad. I am 29 and i am planning to get married. I never had a sexual intercourse before and i am a virgin. Sir, my problem is, the skin on my pennis is not moving back freely. The skin is stucked at the bottom of my pennis, so when ever i get erection and if i move my skin back, i could't control the pain. Even i get a good sperm, but i feel guilty that i could't participate in sex with my wife and i can't make her happy sexually. Is this a very major problem is there any remedy for this. Please help me.
