okay i am a 14 year old gay guy and i too believe that you are born either gay bi or straight. However you may take a while to find whish gender you are sexually attracted to. I myself have been straight gay and bi before and have had relations as each of the above. i am currently gay and iwould advise you to do the opposite of what k_dog2009 says to do. Do not avoid whta your inner body and emotions tell you to do as this can lead to depression thaoght of suicied etc. i myself suffer deperession from doing this and hiding my secret frommy family. i say explore your sexuality andif anyone says it is a " sin " to be gay disregard this as many say God is forgiving (however i am not sure what is said about Alah). i have also been deeply bothered by the thought of a god or greater being who has such power over life as it is and have decided to go by my own religion perhaps i am slighly wierd but what ever suits you and makes you feel comfortable with being youshould be done.
The best of wishes,
Nigel
If you want to step away from being gay, there are many people who can help you. I was gay as a pre-teen through young adulthood. I chose to seek change because I believed that acting out gay desires is morally wrong. There is hope for a staight life for you. I have a wonderful heterosexual sex life, I still love men in many ways, I just choose to not seek sex with them. I would recommend seeking resources on the Web for Overcoming Same Sex Attraction. Look into a group called NARTH
I believe that the current theory is that you are born biologically gay. That is the way you are and you probably can not change it. I am not gay but I have gay friends. I do not think that they could change. I know that you do not live in Europe or USA where gays and the gay life is more accepted now. So, I am not sure how you can handle your life there. Either way, it is my belief (I am not gay and i am not a psycholigist) that you probably can not change the way that you are wired. If you have no interest in girls, you probably should not marry a girl. That would only make you and her not happy. So, you probably would have a miserable life together. If you are gay, and happy, accept it and live your life accordingly.
As I see it you should change yourself the only one who can help you in the matter may be a psychologist, however this is doubtful. If you want to change find your own powers to do it.
Best wishes, John
