Bad Boy,
You can't judge people in Nepal just like that. It is all about culture. Holding hand of another guy by a guy is considered as Taboo here in USA but it our culture back in Nepal. You can't say USA culture is 100% right and our culture is 100% wrong.
By touching hand of a friend add more friendship and won't make you gay.
Here is the statistics,
USA or Europe ( where holding a guy's hand is considered as gay) have more depression than any other country in the world ( i am not sure but it is my rough estimate).
If you ask me a question which culture is the best (nepal vs USA), then I would go for Nepal
