Decide or Born Gay?

[Greek]

Research says you are born what you are. But I know people who say they decide one day I am going to start liking guys because so many women have hurt them. From your feedback what is really going on here? Can someone just change there mind one day to the same sex? To clear up this post, I don't want to become gay. Other people I know have given up on girls. So I am looking into this. There We Go!
