Sex is a strong constituent of overall satisfaction in life, according to a new poll.
The Pfizer Asia-Pacific Sexual Health and Overall Wellness survey quizzed more than 3,000 sexually active men and women in Asia-Pacific countries.
Most people insisted sex was very important for a happy marriage.
However, it was also learnt that 57 per cent of men and 64 per cent of women polled were not satisfied with sex.
Sexual dissatisfaction, among both men and women, was primarily related to erectile dysfunction (ED).
"In half the men polled, there were missed opportunities to assess cardiovascular diseases (CVD)," The New Straits Times quoted associate member of the British Association of Urological Surgeons Professor Michael Kirby, as saying.
He added: "Men with ED should be specifically targeted for CVD preventative strategies in terms of lifestyle changes and pharmacological treatments. To some extent, we are still pre-historic in handling this problem.
"Frequent intercourse is a healthy thing to do. Quantity is very important to men but quality is important for women.
"The survey also showed that ED was associated with satisfaction with sex, love and romance, family life and role as partner -- for men and women.
"Men with ED have sex less often, are less satisfied with sex and other aspects of the sexual experience, and are less positive about life overall."
However, Kirby insisted seeking medical help can be helpful.
He said: "Many patients are reluctant to seek help because they believe it would not be recognised as a medical problem. Some also fear that discussing sexuality may embarrass their doctors and themselves. But we need to raise this iceberg above the surface."
