EJ, I’m talking about the many posters on this and other message boards who have identified themselves as permanently heterosexual (and often married) individuals. No, they’re not latent/closet gays.
I’m distinguishing these from the ones michelle correctly describes, and many of us on CAF have also interacted with, who may be temporarily questioning their sexuality and do come on here to post.

Not.
If you say so. For the record, though, parenthood is not proof of typical sexuality.
I know at least one married father of children who decided after 20 years that he needed to be in a dress and be addressed as “she” in order to happily continue his high school teaching job. He is undergoing hormone therapy and at last report hoped to have the outward indications of his gender surgically altered. You know there are others who are not transexual or transvestite, but who are homosexual, but they get married and have kids, anyway, because they decide they want to or think they’re supposed to. Some of them do not go through a midlife crisis, abandon their marriages, and find a same-sex partner. Some stick it out for life. It is amazing what you can accomplish, when you put your mind to it.
And no, I’m not saying that changing who you are attracted to is one of those things that you can automatically do by “putting your mind to it”. I’m saying that the history of arranged marriage, if nothing else, proves that when the social mileu is right, marriage, procreation and mutual personal attraction do not have to go together.
Yes, a lot of the people posting here are heterosexuals. I fail to see how it is that they have no stake in deciding the terminology describing homosexuality. It is not as if homosexuals can expect to have the floor to themselves when the subject is homosexuality, any more than the parents have found it remotely possible to command the floor with regards to childrearing, but whatever.
I just think it is a good idea to remember that there is no physical test that can prove sexual orientation one way or the other. As long as that is true, then sexual orientation will be like pain: self-report will be very hard to prove or disprove, and that inability to provide independent confirmation will mean that all self-reports will be more or less subject to suspicion. It can’t be helped.
