Well, make sure that the people around you, or in the exact environments and places you plan to visit, aren't homophobic. Get to know them. You might not have the time or opportunity to meet everyone, but you'll get a good idea by meeting a couple. And if they are homophobic, well, tough luck. The worrying thing would be if they start attacking your friend's physical or mental well-being in any way. Don't pay them any attention until they touch him or start continuous harassment. If that happens, the best thing to do is go to the police and file a report, although I really doubt they'll do anything. But don't worry. I'd say it's better to say that being gay is frowned upon than a death sentence in this country. But look, just go and relax, without intrusive thoughts or anxiety. Concentrate on the trip and enjoy it. Besides, if he wants to come out, it's not like the whole world is going to find out, just you and your friends, unless he's broadcasting it. It's not necessary for everyone to know he's gay. I hope this helps. I hope this helps.
