I think of my brother as being attractive.
Why do you think of him as being attractive to you?
I can't help myself.
Being attracted to your brother is strange and different. Obsessing about him in this way will lead you down a dark path.
I'm going to tell my whole family, my friends and everyone on the internet. I'm tired of hiding my feelings for him.
I think that is a bad idea and completely unnecessary. This could upset and embarrass your brother. I think it will be a better idea to tell this to a therapist instead.
