An ordinary individual who finds himself attracted to both genders is commonly referred to as bisexual. However, it is indispensable to mention here that a fairly large population of the world may have small episodes or experiences of being attracted to both genders and are not categorized as bisexual. While some people prefer to put a vivid label on themselves as being straight or gay, others may want to explore their sexuality at times. Since our society still lacks the maturity of accepting bisexuals at all times, it is rather difficult for such an individual to come out as one. This is what leads to isolation in some of the scenarios. However, rest assured, it is to be kept in mind at all times that being bisexual is nothing to be ashamed of. There is nothing wrong about being bisexual or even feeling it for a while for that matter.
There is 
no argument over the fact that bisexuality certainly is a normal aspect of the wide spectrum that human sexuality has to offer. As of now, medical sciences have failed to come with an explanation as to why would a person feel bisexual while others don’t. However, the important thing to keep in mind at all times is that being bisexual is certainly not a disorder or a disease that has to be treated or cured. It is your right to be treated normally if you happen to be one and it’s your responsibility to treat your folks normally one of them happen to be bisexual.
It is of prime importance to accentuate that bisexual may as well be a limited label for a number of people since it considers the possibility of only two genders as far as the spectrum of human sexuality is concerned. Therefore, a number of people prefer to make use of the term pansexual to imply that they are attracted to entire human kind regardless of the gender or perhaps polysexual that implies that they are attracted to a number of different genders that human sexuality has to present. Understanding these terms, therefore, is an important aspect.
Understanding or identifying yourself as bisexual may not be as easy as it may seem to be. As a rule of thumb, if you find yourself consistently attracted to both genders in a sexual fashion, you may identify yourself as bisexual. However, it is to be kept in mind that the feelings of attraction may not manifest for both genders at the same time and there may as well be a difference in the intensity as well. Therefore, it is important to stop denying the feelings that you are experiencing and play around with your sexuality before concluding anything.
Last but not the least, a bisexual person is highly likely be in a successful monogamous relationship with a person of the same or opposite sex. It is absolutely not necessary for a bisexual person to be in a relationship with a person from both the genders at the very same time. The myth of monogamous relationships being impossible with a bisexual partner must be debunked.
