There's great appeal in the idea of a man walking up to you, introducing himself, and telling you that from the moment you walked in the room he's been unable to take his eyes off of you. If that line is even half true it means he's really into you and you can damn near get high off of that kind of admiration. That's why so many men will go to a gay bar or a club and simply wait around for someone to make the first move. Step four is about putting that practice to rest. Sure, it's nice when someone is interested enough to do that but it's such a tiny part of what your overall relationship will hopefully be that it's not worth costing yourself a chance to meet lots of guys. You need to be confident and even aggressive when it comes to meeting guys.
Imagine yourself at any sort of gathering where lots of gay guys are present. It could be a bar, mixer, club, etc. There are going to be guys there that you're attracted to. Step four is about having the confidence to approach one of them and start a conversation. If that doesn't work out then move on to the next guy. Unless you're an absolute troll or you can't form a complete sentence you'll end up with a phone number or a date or some hot gay sex by the end of the night.
Of course, all of that is easier said than done. Not everyone has the confidence to walk up to someone and introduce themselves and few men have the conversational skills to come up with dozens of things to talk about in a single night. When in doubt you can never go wrong with a compliment. Keep it really simple (I like your eyes, your suit is amazing, etc) and launch right into an introduction. Have a second line prepared immediately (isn't this song great, are you friends with the host of the party, etc) and you'll have broken the ice. If he's interested he'll likely ask the next question or a conversation with genuinely develop and you can get to know each other.
If you're looking for a specific type of guy then you can launch into a conversation that pertains to him. If you want a jock then go ahead and ask about sports and see what happens. If you're into artists then ask about their work. Sometimes gay guys have no interest in talking about their careers in a social situation so you have to be careful when asking about that stuff. Generally if it's something they feel proud of they'll be happy to talk your ear off because they want other people to understand why they're proud. The key here is to do this over and over again. The more practice you get the better you'll be at approaching guys, charming them, and getting whatever you want, whether that be a nice of gay sex or a chance to meet lots of gay guys and end up dating one of them.
You know what kind of man you want to date. You've done research on gay sites and you've fantasized about Mr. Right. You've transformed yourself in the best version of you possible. You're brimming with confidence. You've started talking to ....
