Not strange to me at all for the simple reason that I can imagine that many visit this site and have tried out the ex-gay thing at one or another.
I believe that research is a worthy endeavor.
Sorry I can't participate. When I realized I was gay after attending Evangel College (a Pentecostal school), I sought out a counselor to help me get me out of dodge. I didn't go the ex-gay route.
Be the love you seek.
