Q: I am a healthy male of 33 years with a steady sex partner. We have sex once every fortnight. What is the normal number of times one should be able to have sex say in one session of about 2 hours? I am able to do it only once in a session. How does one increase libido without taking recourse to drugs like Viagra, which has side effects?

A:There is no "normal" frequency of sexual intercourse. It depends upon many factors. However, usually a gap of 1-2 hours often exists before a male can have good enough erection once again. Have a good, healthy life by observing certain basic precautions: Exercise regularly, eat a balanced diet, don't smoke or drink, keep yourself active, keep your body weight within normal range. These will help in maintaining a good libido. Equally important is that you and your partner should have a good & affectionate relationship. That is the best libido enhancer Contrary to popular belief, drugs like Viagra don't increase libido.
