How can I improve my sexual performance?

Q: I am 24 years old and have a girlfriend. I had sex with her thrice but unfortunately I could not perform well in bed. I don't know why but I could not hold my self after 4 to 5 strokes only and everything was spoiled. I am very frustrated about the size and stiffness of my penis. Please shed some light on this and let me know if there is anything I can do. I do understand that sex is not so important in life than having a good relationship but at times it does play an important role. Please advise some pills or something so that I can improve my sexual performance.

A:I am not sure if I agree with you about sex not being important in life if the man-partner relationship is otherwise good. In fact, good sex contributes to a good relationship and can adversely affect a good one if chronically unsatisfactory. You seem to be suffering from both premature ejaculation and erectile dysfunction. If you are a first timer, these might be anxiety-related, but it would be unscientific to presume that without a proper andrological evaluation since there’s no previous benchmark for comparison. Obtain a short-term prescription for Viagra. It might help you tide over your starting troubles. If not, you'll need assessment.
