Are there gay men who are happily married with their female partner?

If we were to look at this question in a philosophical perspective, a gay man will not be happy in a romantic or sexual relationship with a female. This is because they are attracted to members of the same sex, not the opposite sex. They may love their spouse as a best friend, but that's as about it.

Even if they are married and have raised children, they are still gay and will only lead healthy and satisfying relationships with other men.
