Because some narrow-minded folks feel that if it is a choice, the person should simply "choose" to be heterosexual.

because it gets those haters off my sisters, I mean the gays back.

Actually SOME do choose to be "gay". There are two main things to consider here. 1. Most of us fall in a very broad plain of bisexuality. The reality is that the minority are 100% straight or 100% gay. Most of us are shades of or ratios between the two points. 90% straight 10% gay. Meaning we identify with being say "straight" although we could (and some secretly wonder about it) have gay sex. In cases of near balance between the two points we find "bisexuals". Bisexuals are no different than the majority who cling to their self imposed sexual identity, however they have come to grips with the reality of their nature. Many will (and do) side with either gay or straight depending on who they are with at the time. 2. Situations or experiences can push a person either way. EXAMPLE: a woman is a victim of rape by a man - in order too actually live or have any hope of finding love, she identifies as a lesbian, and for the rest of her life "shuns" men. Ones self identity has much to do with this. There are men (and women) who proclaim loudly and go on for ever that they are 100% dyed in the wool straight. Even when they are caught in the act of homosexual sex, or in the act of soliciting homosexual sex say in an airport bathroom. In these cases the person can (and most often is) in a marriage - meaning they adopted the "straight" way of life which is marriage, kids, pretending to be 100% dyed in the wool straight with no homosexual leanings at all. Their "identity" is straight and even when they are got "red handed" they are still straight. A person who is born 100% straight can not be gay, can not perform gay sex at all. They can not make a choice and decide one day to be "gay". No way, no how. It is impossible for them. A person who is born 100% gay can not perform straight sex, no way, no how - it is impossible for them to make a "choice" and decide to be straight. People who are say 90% one way and 10% the other way do, on one level or another, make a choice to follow a certain path. They will tend to follow the 90% part of themselves. Although they may have a leaning toward, or be able to think about and even able to perform in their 10% mode they won't and should be considered as "unable" to make a choice. But we also have to consider that human sexuality goes hand in hand with relationships, partnerships with who we are able to form a loving, committed "love interest" with. Many who claim 100% dyed in the wool homosexuality are in reality only a larger percent "gay". They can (and many do) participate of straight relationships. However they are not satisfied with that relationship, they are not "happy" being with a person of the opposite gender. It doesn't have everything to do with sex, there are many aspects to each gender that makes one more attractive than another, some are chemical/physical in nature, others are mental/emotional in nature. Sexuality is a very complex thing, and we have only spent the last 50 years doing any real research into it. We have discovered that much of what society accepts about genders, relationships and sexuality is bogus - false - myth-leading. However those myth-conceptions and bogus "facts" are part and parcel of what humanity is - we have become so mixed up when it comes to sex and "normalcy" when it comes to perceived sexuality that it does play a huge roll in how we interact with one another. It affects the "choices" of individuals, so the many who do fall in the wide broad field of "bisexuality" are "forced" by the conventions of society to choose one path. Most are comfortable with that path and accept it graciously, many however are not comfortable with it and either fall to secret sex acts on the side, or become extremely opposed to bisexuality and homosexuality.

It doesnt work that way. The attraction to the same sex is encoded either in our genes or permanently in our personalities. You cannot choose your sexuality, it is set in stone what you are born with. Otherwise if someone is truely attracted to the opposite sex, and pretends to like being with the same sex, then they are lying to themselves, and they will eventually go back to the opposite sex, instincts kick in eventually. I pretended for a while that I was str8, in order to fit into the crowd I wanted to be in, but true as the sands of time I went back to guys. You even without the hetero, or homo genes cannot choose to be the other, eventually your natural instincts will override the choice.
