Trust me, if one of those 5 girls had doubts you probably wouldn’t know it.  I’m 18 and the president of my class (have CAH) and nobody would ever know I had struggles with my sexuality.  I’ve had boyfriends, talked of crushes, and still am attracted to guys.  As for everything else, I agree with you that some may use CAH as a crutch.  I believe homosexuality is wrong and going through with attractions towards the same sex is wrong.  However, people don’t what they are tempted with.  It is what they do with that temptation that matters.  It is not fun being attracted to your friends and living under a dark cloud.  Sometimes it is just nice to read that others are fighting the same battle.
