I am so tired of the whole, being gay is not a choice. WHAT? Of course it is. Being straight is a choice, being a Morman is a choice. Everything we do in life is about choice. We are born blank slates and OUR perception of beauty and companionship develops based on our experiences.
There is consensus, both scientific and psychiatric, that sexuality is not a choice. This is NOT the same as saying it's there from birth.

American Academy of Pediatrics said:
The mechanisms for the development of a particular sexual orientation remain unclear, but the current literature and most scholars in the field state that one's sexual orientation is not a choice; that is, individuals do not choose to be heterosexual or homosexual
(Above link is supported in this claim by the Journal of Adolescent Healthcare).

Royal College of Psychiatrists said:
It would appear that sexual orientation is biological in nature, determined by a complex interplay of genetic factors and the early uterine environment. Sexual orientation is therefore not a choice.
Royal College of Psychiatrists said:
A small minority of therapists will even go so far as to attempt to change their client?s sexual orientation. This can be deeply damaging. Although there is now a number of therapists and organisation in the USA and in the UK that claim that therapy can help homosexuals to become heterosexual, there is no evidence that such change is possible.

(The American Psychiatric Association, distinct from the American Psychological Association which I linked above. In the above link, they state there is "no published scientific evidence supporting the efficacy of reparative therapy").
Michael King said:
The conclusion reached by scientists who have investigated the origins and stability of sexual orientation is that it is a human characteristic that is formed early in life, and is resistant to change. Scientific evidence on the origins of homosexuality is considered relevant to theological and social debate because it undermines suggestions that sexual orientation is a choice.

Statement by American Psychological Association said:
Sexual orientation has proved to be generally impervious to interventions intended to change it, which are sometimes referred to as "reparative therapy". No scientifically adequate research has shown that such interventions are effective or safe.
(The above statement is supported also by the Counselling Association Governing Council).

There is significant agreement that one does not choose ones sexual orientation
