I did discuss this topic with my therapist today. She certainly didn't think it was something that couldn't be changed. And she was concerned, too.
I do know people who have homosexual tendencies, yet have been able to be happily married to someone of the opposite sex. They do so for many reasons.
Still, they mainly only have to worry about AIDS. (Not that it should be taken lightly.) Folks with the lifestyle the young lady is leading are really hurting themselves, and it does not sound healthy at all.
We could argue from now to the end of the world. I was just expressing my concerns. I have had my say, so I will move on, and hope for the best for this dear 19-year-old young lady.
