I myself am really scared of how he will react what if I'm wrong and he tells.everyone.or I can take the chance and be with him
I definitely understand the feeling. If you're looking for help, though, could you please expand a bit or ask a specific question?
Lol, poster, do not tell your friend you like him. tell him you are gay and then Only if he also tells you he his gay then you can tell him your feelings.
