@RexRed,
I really do not know what to say about that other than I guess that it may be possible for [some] people to stop being gay if that is what they want but I do not think that it is possible for all people to stop being gay. It would be like trying to stop all heterosexuals from being heterosexuals.
Maybe there are some people that are borderline and they can choose to go which ever way they wish, maybe that is what happen to the doctor but for some reason logic is telling me that he is in it for the money as well!
I think that there is a psychological and a biological component to our sexuality and I do not see how you can change the biological component without some sort of biological change.
