2. Tell Him More About Yourself ... but Not Too Much
Maybe you two really hit it off the first time you went out, and you feel like you can tell him anything. That's cool and all, but don't do it. True, the whole point of a second date is to get to know each other better, yet spilling a ton of personal details won't create true compatibility and can even turn a guy off. "Going on about past relationships, health or debt problems, and hinting at wanting to get married are all buzzkills for a guy," says Diana Kirschner, Ph.D., author of Love in 90 Days. A better idea: Open up about your likes and dislikes and crazy adventures you've had (no monologues, please!). Be sure to give him plenty of opportunities to reveal more about his life and personality.

3. Touch Him Flirtatiously
You spent the first date trading coy comments and one-liners. Now, amp things up by being a little more physically flirtatious. We're not suggesting you rest your hand on his thigh all through dinner. But warm, playful gestures — such as touching his upper arm briefly or giving his forearm a quick, light squeeze — lets him know that you feel comfortable and at ease, says Dr. Kirschner. Once he knows you're having a good time, he'll relax more too.

4. Leave Him Wanting More
If you're really interested in a guy for long-term potential, don't hook up post-date. Really, getting physical too soon can freak a guy out afterward, even if he was totally into you, says Slotnick. Throughout the date, be the seductive woman that you are, but then put the brakes on hooking up so he actually has the chance to chase you a little. Just end the night with a sexy liplock — and know that it will leave him dying to see you again for date number three.
