I haven't read this thread until now, but since I'm about to disappear for dinner to celebrate my 24th wedding anniversary, I thought I should say something....
In the general case, no, I don't think I would want to use this process. As many people have said, being gay is part of who I am.
In my particular case, though, yes, I would use it. Why? Very simply, I'm married to a wonderful woman who I put through hell 10 years ago when I came out to her. In my own way, I love her and I definitely respect her. I would take this process to become straight for her. If I was single, no, but I'm not single. She (unknowingly) sacrificed a lot by becoming married to a gay guy, and then (knowingly) sacrificed more by staying with me when I came out to her. That deserves a sacrifice on my side, and if I could become straight for her, I would. Not for anyone else...just her.
