Find out what kinds of things that she likes to do, and plan accordingly. (Ice skating, the museum, girl stuff like that.)
Touch her in non-threatening ways. (If you are walking to a table in a restaurant, place your hand lightly on the small of her back to guide her. This is a subconscious psychological trick -- it will make her feel closer to you.)
Ask her questions and listen to her answers.
Things Not To DoComplain about other women (ex-girlfriends, etc). In fact, don't complain period.
Stare at her breasts.
Talk about geeky stuff. Repeat, do NOT talk about geeky stuff. Even if you are with a fellow geek.
Take her rock climbing if she is afraid of heights. (I learned this the hard way.) Jezelf zijn lijkt me nog steeds de beste tip, maar ben je echt wanhopig dan heb je mi chien wat aan deze tips.
