Crazy insane hypothesis: You're not born gay or not gay

If it can be unlearned, why don’t we have more evidence of people who have successfully changed their sexual orientation? It’s not like no one has ever attempted this before.

Here’s some info from a study I looked up for a previous thread:

And these weren’t all, or even mostly, teenagers forced into religious “ex-gay” programs by their families. About three quarters of the people in this study had sought out “ex-gay” therapy for themselves, and a majority saw licensed mental health practitioners.

ETA:

I’d be interested to see a study showing that changing one’s religion causes significant long-term psychological harm or drives people to attempt suicide.
