it would have been better if your statement was something like "i would like to go on a tour to qatar and maybe also, while i'm already there-- hook up with this guy who lives in doha who ive been talking to over the internet", then go with your concerns. maybe you'd get less bashing answers to your query in the coming days.
you see, it reads as if you're flying in all the way from US for a booty call. QLers will be a little hostile at you. (by the way, if you really are just flying in to meet this man, in my opinion from one woman to another [i know this is not one of your main concerns but..]-- it's not worth it. that's just me. why not have him visit you there instead? just a thought.) good luck!
