What is the best way for a girl to make the first move on a guy??

I like the conversation one. Asking if they're single is another way that immediately lets them know you're interested in getting to know them better. If they're not single, or if they hesitate because they're dating someone, then you have to know ahead of time preferably how you're going to proceed. If you're willing to try to pry them away from someone, or make them cheat, then you have to be prepared to be flirty and be rejected and walk away if that's how they respond. Give them you're number or tell them where you work or how to get a hold of you if anything changes. If they're single and they're interested in you, then they'll certainly tell you. Grabbing their junk is likely to disgust a man as much as it is a woman, believe it or not. Most men probably wouldn't admit to this, but it's true. If they're single and you are too, then you have something in common. Point that out. "Hey we have something in common, I'm single too. Maybe we could get a drink sometime. Can I give you a call? Or maybe I should give you my number?" Something along those lines. Unless you're up for something then and there, but you also don't want him to think you're a one-night-stand (unless you do) or a slut or that you do this often. That's my advice ... Have you told him yet?
