I have spent a lot of time in the middle east and Doha is a bit less liberal than Dubai. Get a massage only from the licensed masseur who works at your hotel, don't take chances in any outside spas. Most of the international hotels have bars, if you make eye contact have a drink with another patron and get to know him better but in NO CASES ever be aggressive. Your best bet is to meet another Non local, forgot the local muslim guys, they would flip and call the police in a NY minute !!! If you go to Dubai, lots more choices there like the bar in the Le Meridian hotel near the airport which has quite a large gay following but again just be conservative, never do anything out in public you don't want to be held accountable for by the authorities. Everything goes fine until it doesn't. !!!
