Does affirmations work regarding sexual orientation?

I see that even here on this forum there homophobes... I am gay and i don't ask straight people to get rid of their heterosexuality. Many people need education on LGBT issues...

No obviously it doesn't. Your sexuality is highly dependent on your genetics and your childhood fantasies. Whatever you were attracted to in your early teen years and puberty.. That is your true sexual orientation. 

A better question why would you want to brainwash yourself into changing your sexuality? Whether you're gay or straight.. Do you feel like you're attracted to something you aren't "supposed" to be attracted to?
