I am a 29 years old male, married a week before. Before marriage, me and my wife both were virgins. I had my first sex yesterday which was bit of hot and cold. I didn't had any difficulties while the foreplay which lasted fairly about an hour and my penis was harder during the period. However, while having the intercourse it quickly resulted in ejaculation without entering my penis into my wife's vagina. I have uncircumcised penis and skin on the head of my penis doesn't slide back and is very sensitive. What should I do? Also I think size of my penis too big for the hole in my wife's vagina. Thanks.
