COSMO'S GUYS YOU THINK YOU SHOULD DATE... BUT SHOULDN'T

• Adrenaline Junkie -- This dude skydives, surfs, runs with the bulls anything for the rush. And he has the sick abs and chiseled arms to prove it. But to keep him happy, you need to be in perpetual motion, too. This guy does not like to sit on his ass and he doesn't like for you to sit on yours either. And it isn't just a phase. In his late 30s, he'll get into marathons, and they'll lead to triathlons and eventually to the Ironman competition. Yeah, that means a trip to Hawaii but instead of chilling on the beach, you'll be cheering him on from the sidelines. Having fun yet? 

• Nice Guy With a Chip on His Shoulder -- He'll ridicule the "tools who are trying too hard" with bold clothing choices to seem down-to-earth, but here's his dirty little secret: He spends just as much time picking out his outfit as his more fashion-conscious counterparts do. Under the casual exterior is a calculating killjoy with mom issues. He'll stand at the bar, thinking 'Why is that girl going for that dude over there? One day, she'll come to her senses and get with a nice guy like me!' The truth is, he's so preoccupied with being overlooked that he'd be totally oblivious to your attention. 

• Smooth Operator -- He's the type that rolls up to the club in an Escalade and holds court in the VIP section, ordering bottle service all night. Though he got Ds in high school, he now scores A, B, and C cups with entertaining small talk and name-dropping. Yeah, he's a Casanova in a skull cap, it replaced his trucker hat about a year ago. But this lid spells trouble. It takes confidence to pull it off with a straight face, too much confidence. There "is" such a thing. He'll shower you with attention, but beware: You may not be the only chick in that shower. 

• Workaholic Hotshot -- This guy is always dressed to the nines, because he's loaded. Simmer down the cash flow comes at a price. He toils until the wee hours, then loosens his tie and parties like there's no tomorrow. Unfortunately, there is tomorrow, and it starts in like three hours. What little time he has for you will be shared with his BlackBerry. The ugly truth: Money is the love of his life, and you're just a mistress or second mistress, since he's probably crunching more than numbers with his secretary. (Cosmopolitan)
