is there a confusion about being gay or bisexual?

[SUPERNATURAL]

some people say there is no proofs that gays are born like that.. what about bisexuals? do they born or they choice? some people confuse me.. there are no proofs of gay people are born like that.. someone say in this forum. maybe at point of his childhood.. he has an experience with the same gender.. it might be gay or bi.. as well I heard some people can be confused all their lives about their sexuality.. btw I am gay.. so if gay is born.. then bisexual people? choice or born?
hello? someone there?

There is proof, it has been scientifically proven. It has something to do with a persons Hypothalamus.
