Some gay men do, and some don't.
Gay men generally only marry women to hide their orientation.
It's almost always done to hide their sexual orientation.
As of 2011, gay people can freely join the US military and do not have to hide their orientation.
Being gay refers to a person's sexual orientation, specifically when someone is attracted to people of the same gender. Men, on the other hand, refers to the male gender. Gay men are men who are attracted to other men. So, "gay" describes a specific sexual orientation within the context of men.
Gay men already are normal, so there is nothing to "return" to. But if you are asking how many gay men change their sexual orientation, the answer is zero.
Nobody can "become: gay. Sexual orientation is not changeable. It works the same for both men and women.
Yes. There is no logical reason to hide anyone's orientation.
Nobody can "opt" to be gay. It is not possible to change sexual orientation.
Although sexual orientation (whether a person is gay or straight) may be genetically determined, there's no statistical evidence that gay men are more likely than straight men to have gay children.
There is no specific percentage of men who "turn gay" in prison. Sexual orientation is a complex aspect of a person's identity that is not determined by their environment or experiences. It is important to avoid perpetuating stereotypes about sexual orientation and prison experiences.
It is not usual but no it does not make you gay. If you are male and are attracted to men then you have a homosexual orientation.
I do not believe so because gay means a man whose sexual orientation is to men, and a lesbian is a homosexual woman.
