Physical intimacy is a very important part of our lives and defines how we relate to others and see ourselves. It is the attraction one feels towards a particular gender or group of people not just romantically, but emotionally and sexually. There is an increase in the number of people in today's world who identify themselves as bisexuals. Bisexuality is the romantic and sexual attraction or behavior towards people of any sex or gender i.e. both males and females. There are many factors that affect the sexual orientation of a person including environmental, hormonal, emotional and biological factors. Bisexuality is not a disorder that needs to be treated, nor are bisexuals psychologically disturbed.
One very misleading myth is that bisexuality is just a phase and after experimentation (usually during college years) you settle for your true identity as either a homosexual i.e. attracted towards the same sex or heterosexual i.e. attracted towards the opposite sex. Bisexuality is not a transitional period. Most bisexuals may act on their desires and choose to be with one particular sex. However, it doesn't mean that bisexuals are not attracted towards the other sex. This does not mean that they are any less faithful towards their partners than other sexual orientations such as heterosexuals, homosexuals, pansexuals etc.
Several surveys later, it has been concluded that women are more likely to identify themselves as bisexuals than males. This is because women have greater erotic plasticity as compared to men. Bisexuals are often prejudiced against and are stereotyped as highly promiscuous and sexually confused. There is also a social stigma attached to the concept of bisexuality. This is nothing more than an unfair social bias. If you wish to discuss about any specific problem, you can consult a sexologist.
