I have done so, and it was one of the worst things I've ever seen. My former comment may have seemed cruel, but one of the things I noticed when I took my friend's address book after his death and started calling his friends and customers to let them know he had died was the sheer number of guys who had fled the lifestyle as soon as the AIDS thing hit town and had gotten married and had children.
As the above post indicated, it's not that some married gay or formerly gay guys aren't on the down low. But if they can function in a marriage well enough to stay married and have children, surely there is hope for healing.
My friend had been a strong, 6 foot tall man who restored houses and built all kinds of mechanical things with great skill. To see him reduced to hallucinations before death and and 73 pounds at death was devastating. I will always miss him. We had been like brother and sister for decades.
...and had homosexual affairs on the side, in the process putting their wives (and potentially their unborn children) at risk for HIV as well.
Closet cases are the number one reason why there's any HIV at all among heterosexuals apart from IV drug users sharing needles. And the AIDS/STD angle aside, I've always thought that closet cases like Larry Craig who keep up appearances with a sham marriage are even more off-putting than somebody who is openly homosexual.
