Hello , 2 years back I got married. My problem is after my marriage, I was very good at sex, sometimes we had 4 to 5 times in a day also. But, from the last couple of months I am facing a problem. If I have sex at night and very next day also, if my partner also wants me to do sex, I am not able to ejaculate the sperm. I am trying very hard for few minutes also but I am not getting it instead of that I am getting some pain also while doing sex. And one more thing, Overall my marriage life is happy but I Ejaculate very fast with 5 to 10 mints. So kindly help me doctor.
