I wouldn’t even say relapse.....if you’re gay you’re gay. There ain’t no praying away the gay in my mind.
And yes, HIV would be very scary.
My mother belonged to a Republican women's group and my father would go to the meetings with her. After her death he continued to attend and I sometimes went with him. One month the speaker was an "ex-gay" man. He seemed very sincere. That was more than 10 years ago and I don't remember his name.
