LGBT: I wanna add this guy on my facebook but at the same time Im discrete..?

Lol I doubt someone would message all your friends and tell them that you're gay...especially if its another gay guy...Just add him, and send him a message saying how you're in the closet and to not say anything on your public profile which would cause people to suspect that you're gay/bi :)...I have plenty of other gay guys on my facebook friends, and I'm not even fully out the closet...If worst comes to worst, you can easily block him from being able to write on your wall, or even delete him from your friends list all together if things get that crazy, but I really doubt that that'll happen :)
