I was just watching this YouTube vid, featuring an ex-"ex-gay" man. In it the man talks about his therapist having him snap a rubber band on his wrist each time he finds another man attractive.
I post it because it reminds me of my own experience as a teen, when I finally got up the guts to tell the therapist I was seeing that I had sadomasochistic fantasies.
"Imagine touching a boy," he said (I thought I was heterosexual at the time), "and then imagine petting the cat."
Ostensibly, it was to teach me to learn to enjoy touching people gently -- which I was never against doing, anyway.
I tried it all of once. Attempting to conjure up thoughts of my cat while sexually excited did nothing but creep me out.
I never brought up sadomasochism again to that therapist. I think I might have told him that I didn't think his method was helpful, but I may not even have done that. I just let the matter drop. I wanted health care -- I needed it, for a lot of other more pressing reasons. So I got the health care, and pretended my sexuality issues weren't there.
