Ask Sexpert: Problem of First Sex

Q: After more than three years of relationship, my girlfriend and I decided to have sex for the first time. Both of us are virgin; I am 26 and she is 22. The problem was that whenever we tried, I could not penetrate her. I lost the firmness of my penis whenever I tried to put on a condom. After two tries, her genitals would start aching. However, I could insert my finger in her vagina. Please suggest how to go about this and what might be the best position to have sex.

A: The standing position can help. A doctor can help you understand better.
