27. DO pay attention.
Guys notice when you're interested in what they're saying, so make sure he's got your full attention. "Give him direct eye contact about 80 percent of the conversation, be positive, and smile easily," says Steinberg. "A group of wild coyotes could break down the door, but you would be too enthralled to notice!"
28. DON'T ask the "five-year plan" question too soon.
"Talking about at what age you'd like to get married and have kids too early in the conversation changes the whole tone of trying to get to know someone," says Jessi Bockting from Louisville, Kentucky. "It suddenly feels like a job interview."
29. DO look for red flags.
"People have a great way of telling you who they are, if you are willing to listen," says Della Casa. "I once knew a woman who went on a date with a guy who jokingly told her he lacked empathy. She brushed it off and wondered why he was so callous with her feelings six months later. If the guy you are dating makes questionable comments, is rude to the waiter, or otherwise sends your gut into a spin, move on."
30. DON'T let him know you've been Google-stalking him all week.
"Look, we know that you've been investigating this guy online since you learned his last name. (We don't blame you, and chances are he's done the same to you.) But if you start in on his alma mater, favorite bands, and how his hair looked in 2004 (which was found thanks to your mad skills at image searching), you are going to creep him out. Big-time."

31. DO casually touch him.
"The way to a man's (or a woman's, for that matter) heart isn't through his stomach, but his eyes," says Alexander. "Humans have evolved to read the emotions of others, and one way we do it is by looking into the eyes. When we touch each other, even with a casual arm stroke or a friendly hug, and look into each other's eyes, we can trigger a series of chemical events in the brain that lead us to open ourselves up to another person. A hormone called oxytocin is released, driving this response. That's followed by dopamine, a chemical that motivates us to seek out rewarding experiences, like being with you."
32. DON'T talk about your ex.
"No good can come of this! You'll seem either bitter, heartless, or still hung-up--and any one of these is a huge turnoff."

33. DON'T apologize for being who you are.
"Why waste valuable cocktail time with your pals with some wuss who can't handle you. Screw anyone who has a problem with that--no discussion!"
