Although is is more difficult said than done, we Nepalese need to stop worry about what others will think and live the way we want. There is nothing wrong in being a homosexual. I am sure you didn't choose to be homosexual.. you're born that way. So there is nothign to be ashamed about. It might be diffucult to come out to your parents than your siblings, I am sure they will understand if you explain to them in detail.

Good luck.
